Gramática de español

Personal subject pronouns (yo, tú, él/ella/usted, nosotros/as, vosotros/as, ellos/ellas/ustedes). Includes formal usted/ustedes and regional variation with vosotros (Spain) vs ustedes (Latin America).

Grammatical gender (masculine/feminine) of Spanish nouns. Most nouns ending in -o are masculine, -a are feminine. Important exceptions: el problema, el día, la mano, la foto.

Regular plural: add -s to vowels, -es to consonants. Words ending in -z change to -ces. Stress shifts may require accent changes (examen→exámenes).

Definite articles (el, la, los, las) that agree in gender and number with the noun. El is used with feminine nouns starting with stressed a/ha (el agua, el águila).

Indefinite articles (un, una, unos, unas) meaning 'a/an' (singular) or 'some' (plural). Often omitted with professions, nationalities, and after ser without adjectives.

Irregular verb 'ser' (soy, eres, es, somos, sois, son) for identity, origin, profession, time, characteristics, and possession. Essential distinction from 'estar'.

Irregular verb 'estar' (estoy, estás, está, estamos, estáis, están) for location, temporary states, feelings, progressive tenses, and results of actions.

Basic distinction: ser for permanent/inherent qualities, estar for temporary states/locations. Some adjectives change meaning: ser listo (clever) vs estar listo (ready).

Irregular verb 'tener' (tengo, tienes, tiene, tenemos, tenéis, tienen) and idiomatic expressions: tener hambre/sed/frío/calor/sueño/miedo/razón/prisa/años.

Present tense conjugation of regular -ar verbs (hablar, trabajar, estudiar, comprar). Largest verb class. Endings: -o, -as, -a, -amos, -áis, -an.

Present tense conjugation of regular -er verbs (comer, beber, leer, correr). Endings: -o, -es, -e, -emos, -éis, -en.

Present tense conjugation of regular -ir verbs (vivir, escribir, abrir, subir). Endings: -o, -es, -e, -imos, -ís, -en.

Highly irregular verb 'ir' (voy, vas, va, vamos, vais, van). Used for motion and to form near future (ir a + infinitive). Takes preposition 'a' before destinations.

Irregular verb 'hacer' (hago, haces, hace, hacemos, hacéis, hacen) with weather expressions (hace calor/frío/sol/viento) and common phrases (hacer deporte, hacer la cama).

Modal verb 'poder' (puedo, puedes, puede, podemos, podéis, pueden) with stem change o→ue. Expresses ability, permission, or possibility + infinitive.

Irregular verb 'querer' (quiero, quieres, quiere, queremos, queréis, quieren) with stem change e→ie. Expresses desire, love. Used with infinitive or noun.

Verbs with e→ie stem change in stressed syllables: pensar, entender, preferir, empezar, cerrar. Change in all forms except nosotros/vosotros.

Verbs with o→ue stem change in stressed syllables: dormir, volver, encontrar, recordar, contar. Change in all forms except nosotros/vosotros.

Verbs with reflexive pronouns (me, te, se, nos, os, se): llamarse, levantarse, acostarse, vestirse, ducharse. Pronoun agrees with subject.

Impersonal form 'hay' for existence ('there is/are'). Invariable for singular and plural. Negative: no hay. Question: ¿Hay...?

Negation with 'no' before the verb. Double negatives are standard: no...nada, no...nadie, no...nunca. 'No' can also mean 'not' in answers.

Adjective agreement: -o/-a/-os/-as for four-form adjectives, -e/-es for two-form. Most adjectives follow the noun. Some have only one form (joven, azul).

Most adjectives follow the noun, but some common ones precede: bueno, malo, grande, pequeño, nuevo, viejo, joven. Some change meaning by position.

Short-form possessives before nouns: mi(s), tu(s), su(s), nuestro/a/os/as, vuestro/a/os/as, su(s). Only nuestro/vuestro show gender.

Three-level system: este/esta/estos/estas (this/these near speaker), ese/esa/esos/esas (that/those near listener), aquel/aquella/aquellos/aquellas (that/those far from both).

Basic location prepositions: en (in/on/at), de (from/of), a (to), con (with), sin (without), entre (between), sobre (on/about), debajo de (under), delante de (in front of), detrás de (behind).

The preposition 'a' before direct objects that are specific people, personified animals, or pronouns like alguien/nadie. Essential Spanish-specific feature.

Mandatory contractions: a + el = al, de + el = del. No contractions with la, los, las, or when 'el' is part of a proper name (de El Salvador).

Question words (all with accents): quién (who), qué (what), dónde (where), cuándo (when), cómo (how), por qué (why). Yes/no questions use intonation or inversion.

Question words for quantity: cuánto/a/os/as (how much/many), cuál/cuáles (which/what). Cuánto agrees in gender/number; cuál often replaces qué before ser.
