Part 1 · Elements of a Sentence

Nouns, Articles, and Adjectives

Every Spanish word has a gender. Once you feel it, you'll never lose it.

Every Spanish noun has a gender, masculine or feminine, even objects. Gender decides which 'the,' which 'a,' and how adjectives are spelled: rojo, roja, rojos, rojas. Adjectives usually follow the noun (carro rojo), the opposite of English; you'll describe any room, person, or city correctly by chapter's end.

Gender: Every Noun Has One, and It Controls Everything Around It

What You're learning that every Spanish noun is either masculine or feminine, with no exceptions, and that this single fact decides which word for 'the' goes in front of it: el for masculine, la for feminine.

Why Gender isn't trivia, it's the hinge the sentence swings on: articles, adjectives, and later pronouns all must agree with it; get it wrong and native speakers will still notice, the way 'she is a boy' jumps out in English; learning gender with each new word saves relearning hundreds later.

How Nouns ending in -o skew masculine (el); nouns ending in -a skew feminine (la); five endings, -ción, -sión, -dad, -tad, and -tud, are feminine without fail; many common nouns end in other letters and follow no pattern, so learn them with their article glued on as one unit.

In English English keeps gender only in pronouns (he, she, it); Spanish puts it on every noun. Think of el and la less like translations of 'the' and more like a matching outfit for the noun, the way 'a' becomes 'an' before a vowel, except the rule runs on gender.

  • El carro está en el garaje.

    The car is in the garage.

    Carro ends in -o, so it's masculine: el carro.

  • La mesa es de la cocina.

    The table is from the kitchen.

    Mesa ends in -a, so it's feminine: la mesa.

  • La ciudad es grande y ruidosa.

    The city is big and loud.

    Ciudad ends in -dad, always feminine despite not ending in -a.

  • El café está listo.

    The coffee is ready.

    Café ends in -e; its masculine gender must be memorized.

  • La estación queda cerca de aquí.

    The station is close to here.

    Estación ends in -ción, always feminine, and drops its accent in longer forms.

  • El problema no tiene solución fácil.

    The problem doesn't have an easy solution.

    Problema ends in -a but is masculine, a Greek-origin exception.

  • El teléfono está en la mesa.

    The phone is on the table.

    Two different genders, two different articles, in the same short sentence.

  • La mano derecha me duele un poco.

    My right hand hurts a little.

    Mano ends in -o but is feminine, an early exception.

  • El artista pinta murales en el barrio.

    The (male) artist paints murals in the neighborhood.

    Words ending in -ista use el (man) or la (woman).

  • Vale, la reunión es en el piso de Marta.

    Okay, the meeting is at Marta's apartment.

    'Piso' for apartment is a Spain word; Mexico says depa/departamento, Colombia says apartamento.

    Regional · SpainElsewhere: Mexico Órale, la reunión es en el depa de Marta. · Colombia Listo, la reunión es en el apartamento de Marta.

Two Genders, No In-Between

In Spanish, every noun is masculine or feminine, no neuter category. A chair, a decision, a headache, all get sorted into one bucket or the other, and the article in front tells you which.

The definite article by gender and number

MasculineFeminine
Singularel (the)la (the)
Plurallos (the)las (the)

The Reliable Patterns

Two endings do most of the work. Nouns ending in -o are almost always masculine: el libro, el vino, el gato. Nouns ending in -a are usually feminine: la casa, la silla, la cerveza. Learn those two shapes first, and you'll guess correctly most of the time before you've memorized a single article by hand.

Five endings mark a feminine noun almost without exception: -ción, -sión, -dad, -tad, and -tud. La nación, la decisión, la ciudad, la amistad, la actitud. Spot one and commit to la on sight.

Looks masculine, isn't

la mano (hand), la foto (photo), la radio (radio) all end in -o but are feminine.

Looks feminine, isn't

el día (day), el mapa (map), el problema (problem), and most -ma words of Greek origin (el programa, el sistema, el clima) end in -a but are masculine.

Consonant endings are a coin flip

Consonant endings that aren't -ción/-sión/-dad/-tad/-tud follow no rule: el hotel, el café, but la luz, la flor. Learn each noun with its article as one chunk.

Say it as one word

Learn 'lamesa,' not 'mesa,' said fast as one word. Your mouth builds the habit before your brain reasons through the rule, the speed a real conversation needs.

People Whose Ending Doesn't Fix Their Gender

Some endings mark a person and let the article carry the gender instead. -ista (el/la artista, el/la dentista) and -nte (el/la estudiante, el/la gerente) use identical spelling for a man or woman; only el or la tells you which.

Spain

Piso is the everyday word for apartment; a Spaniard would never say apartamento in casual speech, and mesa/silla vocabulary is identical across the Spanish-speaking world.

Mexico

Departamento (often shortened to depa) is the everyday word for apartment, not piso. Core nouns for household objects match Spain's almost exactly.

Colombia

Apartamento is standard, and word choice for basic household nouns overlaps closely with Mexico's, though a few, like carro versus coche, differ.

Spain

Gender assignment itself never changes by country, a table is always feminine everywhere; what shifts is which specific noun people reach for, like piso instead of departamento.

Mexico

Same grammar, same genders. The vocabulary leans toward departamento, coche or carro (both heard), and computadora rather than ordenador.

Colombia

Same grammar again. Colombians say apartamento and carro, and you'll hear computador (masculine) rather than Mexico's feminine computadora.

Plural Nouns: One Rule for Vowels, One for Consonants

What You're learning how to turn a singular Spanish noun into a plural one, and how the article in front of it (el, la) has to switch to its plural form (los, las) at the same time.

Why You'll need plurals constantly, ordering more than one coffee, talking about your friends instead of one friend, describing a city full of buildings instead of a single building. Getting the plural pattern automatic means you're not stopping mid-sentence to work out whether a word needs -s or -es.

How If the noun ends in a vowel, add -s; if it ends in a consonant, add -es; the article changes with it: el becomes los, la becomes las; a few spelling tweaks come along for the ride, like nouns ending in -z changing that z to c before adding -es.

In English English mostly just adds -s too (car, cars), with some irregulars (child, children). Spanish is more consistent: the two rules, vowel-ending gets -s and consonant-ending gets -es, cover the overwhelming majority of nouns with no exceptions to memorize, which is the opposite of English's mess of plural forms.

  • Los libros están en la mesa.

    The books are on the table.

    Libro ends in a vowel, so it just adds -s: libros.

  • Las ciudades son grandes.

    The cities are big.

    Ciudad ends in a consonant, so it adds -es: ciudades.

  • Los hoteles están cerca del centro.

    The hotels are near downtown.

    Hotel ends in a consonant: hotel → hoteles.

  • Las flores amarillas son bonitas.

    The yellow flowers are pretty.

    Flor ends in a consonant: flor → flores.

  • Los lápices están en la mochila.

    The pencils are in the backpack.

    Lápiz changes z to c before -es: lápiz → lápices.

  • Las canciones son de España.

    The songs are from Spain.

    Canción drops its accent in the plural: canciones.

  • Los carros nuevos son caros.

    The new cars are expensive.

    Regional · MexicoElsewhere: Spain Los coches nuevos son caros.
  • Las mujeres trabajan aquí.

    The women work here.

    Mujer ends in a consonant: mujer → mujeres.

  • Los problemas son difíciles.

    The problems are difficult.

    Problema ends in -a but pluralizes with -s like any vowel-ending word.

Vowel Ending: Add -s

When a noun's last letter is a vowel, any of the five, pluralizing it couldn't be simpler: tack on -s. El libro turns into los libros, la casa turns into las casas, and the article rides along: el becomes los, la becomes las.

Vowel-ending nouns: add -s

SingularPlural
el librolos libros
la casalas casas
el díalos días
la personalas personas

Consonant Ending: Add -es

If a noun ends in a consonant, you add -es instead of just -s. This keeps the word pronounceable, Spanish doesn't like piling consonants at the end of a syllable. El hotel becomes los hoteles, la ciudad becomes las ciudades.

Consonant-ending nouns: add -es

SingularPlural
el animallos animales
la ciudadlas ciudades
el trenlos trenes
la florlas flores

The z-to-c switch

Nouns ending in -z swap z for c before -es: el lápizlos lápices, la luzlas luces. Pure spelling, z and c sound the same before e/i.

Accent marks can disappear (or appear)

Adding a syllable can shift the stress, so an accent appears or vanishes. Canción loses its accent in the plural: canciones. Joven gains one: jóvenes. Sound it out; the stress tells you why.

One Special Case: Words Already Ending in -s

A noun already ending in unstressed -s, like el lunes or la crisis, doesn't change in the plural; only the article shifts: el luneslos lunes.

Spain

Same plural rules everywhere; vocabulary choice varies more than grammar here, coche/coches for car being the Spain default.

Mexico

Same rules; carro/carros for car, computadora/computadoras for computer.

Colombia

Same rules; carro/carros for car, computador/computadores for computer.

Spain

The plural mechanics never change by dialect. Where you'll notice a difference is vocabulary: coches (cars), pisos (apartments), móviles (cellphones).

Mexico

Same plural rules. Common plural nouns you'll hear constantly: carros, celulares, amigos, and diminutive plurals like cafecitos in casual speech.

Colombia

Same plural rules. You'll hear carros, celulares, and apartamentos, with a generally clear, even-paced delivery that makes plural endings easy to catch by ear.

Indefinite Articles: un, una, unos, unas

What You're learning the Spanish words for 'a,' 'an,' and 'some': un for a masculine singular noun, una for feminine singular, unos and unas for the plural.

Why You use an indefinite article constantly, ordering 'a coffee,' mentioning 'a friend' for the first time, saying you need 'some tomatoes.' It's one of the first two or three words in almost any request you'll make in Spanish, right alongside the noun itself.

How Same gender logic as the definite article: masculine nouns take un, feminine nouns take una. In the plural, unos and unas both translate to 'some,' and they follow the same agreement rule.

In English English 'a' becomes 'an' before a vowel sound (a car, an apple), a small phonetic adjustment; Spanish un/una isn't about sound, it's about the noun's gender, the same logic that drives el/la; think of it as the indefinite twin of the definite article you just learned: same rule, different word.

  • Necesito un café, por favor.

    I need a coffee, please.

    Café is masculine, so it takes un.

  • Tengo una idea.

    I have an idea.

    Idea is feminine, so it takes una.

  • Busco un apartamento en el centro.

    I'm looking for an apartment downtown.

    Regional · ColombiaElsewhere: Spain Busco un piso en el centro. · Mexico Busco un departamento en el centro.
  • Ella tiene unas fotos increíbles del viaje.

    She has some incredible photos from the trip.

    Unas agrees with fotos, which is feminine plural.

  • Compramos unos libros nuevos.

    We bought some new books.

    Unos agrees with libros, masculine plural.

  • ¿Tienes un minuto?

    Do you have a minute?

  • Vivo con una amiga de la universidad.

    I live with a friend from college.

    Amiga is feminine, so una; amigo (man) takes un.

  • Hay unos problemas con el plan.

    There are some problems with the plan.

    Problema is masculine (despite ending in -a), so unos, not unas.

  • Es un tipo simpático, de verdad.

    He's a nice guy, really.

A, An, and Some

The indefinite article works exactly like the definite one you already know, it just means something different. Un goes with a masculine singular noun, una with a feminine singular noun. In the plural, unos and unas both mean 'some,' matching gender the same way.

The indefinite article by gender and number

MasculineFeminine
Singularun (a, an)una (a, an)
Pluralunos (some)unas (some)
  • un amigo

    a (male) friend

  • una amiga

    a (female) friend

  • unos amigos

    some friends (a mixed or all-male group)

  • unas amigas

    some friends (an all-female group)

un vs. uno

Un is the article ('a car,' un carro). Uno is the number 'one' alone; counting feminine nouns, it becomes una ('one apple,' una manzana). Un shrinks from uno before a masculine noun.

Same brain, new article

You already did the hard part learning el/la. Un/una runs on the exact same gender information, so there's nothing new to memorize about the nouns themselves, just a new pair of words wearing the same rule.

When to Skip the Article Entirely

Spanish drops the indefinite article when stating an unmodified profession, nationality, or religion: Soy estudiante (I am a student), not Soy un estudiante. Add a describing word, though, and the article comes back: Soy un estudiante excelente (I am an excellent student). You'll meet this again once you get to the verb ser.

Spain

Un/una work identically; Spaniards commonly use un piso (an apartment) and un móvil (a cellphone) as everyday targets for this article.

Mexico

Identical grammar; common targets include un departamento, un celular, un cafecito (a little coffee, using the diminutive).

Colombia

Identical grammar; common targets include un apartamento, un celular, and un tinto (a black coffee, a very Colombian word).

Spain

No grammar difference; a Spaniard reaching for this article will often be asking for un café, un piso, or un móvil in daily life.

Mexico

No grammar difference; common phrases include un cafecito (using the diminutive, softer and friendlier) and un departamento.

Colombia

No grammar difference; listen for un tinto (a black coffee) and un apartamento as everyday uses of this article.

Adjective Agreement: Matching Gender and Number

What You're learning how to change the ending of a Spanish adjective so it matches the gender and number of the noun it's describing.

Why Every description needs the adjective to agree: you can't say 'the car is expensive' without deciding -o or -a, singular or plural. Getting this automatic makes your Spanish sound put together instead of a word-for-word translation.

How Adjectives ending in -o change to -a for feminine (rojo/roja); both add -s for plural. Adjectives ending in any other letter (-e or a consonant) stay the same for masculine and feminine, adding -s or -es for plural, the same rule as nouns.

In English English adjectives never change shape: 'the tall man,' 'the tall woman.' Spanish adjectives fit the noun's gender and number, similar to 'this' becoming 'these,' except Spanish does it on nearly every adjective, every time.

  • El carro es rojo.

    The car is red.

    Rojo ends in -o, matching carro (masculine).

    RegionalElsewhere: Spain El coche es rojo.
  • La puerta es roja.

    The door is red.

    Rojo becomes roja to match puerta (feminine).

  • Los carros son rojos.

    The cars are red.

    Add -s for plural: rojo → rojos.

  • Las casas son rojas.

    The houses are red.

    Roja adds -s for plural: roja → rojas.

  • El libro es interesante.

    The book is interesting.

    Interesante ends in -e, so it stays the same for both genders.

  • La clase es interesante.

    The class is interesting.

    Same adjective form, no change needed, because interesante doesn't end in -o.

  • Los exámenes son difíciles.

    The exams are difficult.

    Difícil ends in a consonant; the plural adds -es, like a noun would.

  • Mi hermano es alto y delgado.

    My brother is tall and thin.

    Alto ends in -o here, so it matches hermano.

  • Mi hermana es alta y delgada.

    My sister is tall and thin.

    Alto switches to alta to match hermana; delgado to delgada the same way.

  • Está bien, la comida está rica.

    It's fine, the food is delicious.

Adjectives Ending in -o: Four Forms

An adjective that ends in -o has four possible endings, matching a masculine or feminine, singular or plural noun. This is the group where you'll do the most active adjusting.

rojo (red): all four forms

MasculineFeminine
Singularrojoroja
Pluralrojosrojas
  • el gato negro

    the black cat

  • la gata negra

    the black cat (female cat)

  • los gatos negros

    the black cats

  • las gatas negras

    the black cats (all female)

Adjectives Not Ending in -o: Two Forms

Adjectives ending in any letter besides -o, most commonly -e or a consonant, don't change between masculine and feminine. They only change for number, and they follow the same plural rule as nouns: add -s after a vowel, -es after a consonant.

interesante and difícil: two forms each

SingularPlural
interesante (any gender)interesanteinteresantes
difícil (any gender)difícildifíciles

It's the adjective's ending that matters, not the noun's

A common trap: assuming every adjective needs a masculine/feminine switch. It only needs one if the adjective itself ends in -o. La clase interesante is correct as-is, don't force it into interesanta, that word doesn't exist.

Nationality adjectives are the one extra wrinkle

Nationality adjectives ending in a consonant still change for feminine: español → española. A handful of consonant-ending adjectives break the 'no change' rule.

Match the last letter, not the meaning

When in doubt, look at the adjective's own last letter before you decide whether to change it. -o at the end means it flexes with gender. Anything else means it only flexes with number.

Spain

Same agreement rules everywhere in the Spanish-speaking world; this is core grammar, not a regional variation.

Mexico

Same agreement rules; Mexican Spanish adds diminutive endings onto adjectives very often in casual speech (chiquito, bonitica isn't used here but chiquito/chiquita is common), which still follows the same -o/-a agreement pattern underneath.

Colombia

Same agreement rules; Colombian Spanish is generous with diminutives too (pequeñito), again still following -o/-a agreement.

Spain

Adjective agreement is identical across every Spanish-speaking country, it's foundational grammar, not a dialect feature.

Mexico

Identical agreement rules; you'll just hear diminutive adjectives (chiquito, bajito) layered on top constantly in everyday speech.

Colombia

Identical agreement rules; diminutives are just as common here, especially to soften a description and sound polite.

Adjective Placement: Why 'Red Car' Becomes 'Car Red'

What You're learning where to put an adjective in a Spanish sentence: almost always after the noun it describes, the reverse of English word order.

Why Word order is one of the fastest tells of a non-native speaker; 'rojo carro' reads like a word-for-word translation from English. Flipping the order automatically makes you sound natural.

How Descriptive adjectives (color, size, personality) go after the noun: carro rojo, mujer inteligente. A small set about quantity (mucho, poco, otro) go before, the same spot as in English.

In English English puts the adjective first: 'the red car,' 'the tall man'; Spanish flips the default: *el carro rojo*; quantity words like mucho and otro stay up front in both languages.

  • El carro rojo está en el garaje.

    The red car is in the garage.

    Rojo (color) comes after carro, the default position for descriptive adjectives.

    RegionalElsewhere: Spain El coche rojo está en el garaje.
  • Es una mujer inteligente.

    She's an intelligent woman.

    Inteligente follows mujer, same pattern.

  • Tengo muchos amigos en la ciudad.

    I have many friends in the city.

    Mucho is a quantity word, so it precedes the noun.

  • Necesito otra taza de café.

    I need another cup of coffee.

    Otro (another) always goes before the noun it describes.

  • Vive en una casa pequeña pero cómoda.

    She lives in a small but comfortable house.

    Two descriptive adjectives, both after the noun, joined with pero (but).

  • Es un problema serio.

    It's a serious problem.

    Serio describes problema and follows it, standard placement.

  • Hay pocas opciones baratas.

    There are few cheap options.

    Poco precedes the noun; barato, a quality, follows it.

  • Es un buen amigo, de verdad.

    He's a good friend, really.

    Bueno can precede the noun and shorten to buen.

  • Tiene un carro nuevo y otro viejo.

    He has a new car and another old one.

    Nuevo and viejo follow; otro precedes like a quantity word.

The Default: Adjective After the Noun

A descriptive adjective (color, size, shape, personality, condition) almost always follows the noun: carro rojo, not rojo carro; mujer inteligente, not inteligente mujer. This reverses English default order.

  • el libro interesante

    the interesting book

  • la casa pequeña

    the small house

  • un hombre alto

    a tall man

  • las flores amarillas

    the yellow flowers

The Exception: Quantity Words Go First

A small group of adjectives that tell you 'how many' or 'how much,' rather than describing a quality, go before the noun, matching what you'd expect from English: mucho/mucha (a lot of), poco/poca (little, few), otro/otra (another), and numbers themselves.

Quantity adjectives: before the noun

SpanishEnglish
mucho dineroa lot of money
pocas personasfew people
otro díaanother day
dos librostwo books

Quality (goes after)

un carro rápido (a fast car), una idea simple (a simple idea), un día largo (a long day).

Quantity (goes before)

mucho tiempo (a lot of time), pocas ideas (few ideas), otro carro (another car).

Ask 'what kind' vs. 'how many'

Quick test: does the adjective answer 'what kind' (color, size, personality)? It follows. 'How many'? It precedes. Otro (another) really means 'how many,' so it goes first.

A few common adjectives can go either way, later

Bueno, malo, and grande can move before the noun and shorten (un buen amigo), slightly shifting meaning. That's covered later; for now, default to placing adjectives after the noun.

Say the noun, then paint it

Picture pointing at the noun first, like handing someone a plain object, then describing it: 'car... red.' That mental order matches Spanish word order and will help the habit stick faster than memorizing a rule.

Spain

Same placement rules; you'll hear un piso pequeño, un coche rápido, following the standard noun-then-adjective order.

Mexico

Same placement rules; diminutives sometimes replace an adjective entirely in casual speech (un cuartito instead of un cuarto pequeño), but the underlying order doesn't change.

Colombia

Same placement rules; expect plenty of warm, descriptive adjectives after the noun, un carro bacano (a cool car), following standard order.

Spain

Word order for adjectives doesn't shift by country, it's core grammar; Spain just leans on a slightly different everyday vocabulary to fill the adjective slot (guay, majo).

Mexico

Same word order; Mexican Spanish often reaches for chido/padre in that final descriptive slot instead of guay.

Colombia

Same word order; Colombian Spanish reaches for chévere/bacano in that slot, and often adds qué pena as a softener elsewhere in the sentence, not as an adjective itself.
