Spanish grammar, step by step
A guided tour through Spanish grammar with glossed examples that show how each piece of a sentence fits together.

Spanish is a language of patterns — learn the pattern once, and you can say thousands of things.
The verb does the work
verb endingsThe ending of the verb changes each time — but the beginning stays the same. Can you figure out who's speaking from the ending alone?
Spanish verb endings encode the subject. In most sentences you don't need a separate pronoun — the ending is enough. This is the single most important pattern in the language.
Adding an object
word orderWhat comes after the verb in each sentence? Is it the same position as English?
Spanish word order is Subject–Verb–Object, the same as English. The subject is often invisible (the verb ending tells you who it is), so sentences often start directly with the verb.
Every noun has a gender
gender + articlesThe word for "the" changes between the first and second examples. What else changes alongside it?
Every Spanish noun is either masculine or feminine. The article ("the") must match. Most nouns ending in -o are masculine (el libro), most ending in -a are feminine (la casa). Learn the article with every new noun.
Singular and plural
plural agreement| Singular | Plural | |
|---|---|---|
| Masculine article | el | los |
| Feminine article | la | las |
| Noun ending | -o / -a | -os / -as |
| Verb (3rd person) | habla | hablan |
From "el libro" to "los libros" — how many things changed? And what happened to the verb when more people are speaking?
Plurals ripple through the whole sentence — article, noun, and verb ending all shift together.
Tense lives in the verb
tense endingsThe stem "habl-" stays identical in all three sentences. What is the only thing that changes to shift the meaning from present to past to future?
Tense, person, and number are all packed into the verb ending. Swap the ending and the time changes — no extra words needed.
Negation is one word
negationCompare the first and second sentences word for word. What is the only addition?
Place "no" directly before the verb. That's all. Spanish also allows — and sometimes requires — double negatives: "no... nada" means "not... anything", and both words must appear.
Describing things
adjective agreement| Form | Ending | Example |
|---|---|---|
| Masculine singular | -o | libro rojo |
| Feminine singular | -a | casa roja |
| Masculine plural | -os | libros rojos |
| Feminine plural | -as | casas rojas |
The adjective changes its ending between the examples. What is it tracking?
Adjectives come after the noun and agree with it in gender and number.
Asking questions
interrogativesThe first example has exactly the same words as a statement — only the punctuation differs. What do you think changes in speech? And where does the question word go?
Yes/no questions use the same word order as statements — just rising intonation (and ¿ in writing). Question words — qué (what), quién (who), dónde (where), cuándo (when), cómo (how), por qué (why) — come first and carry a written accent mark.
Objects become pronouns
direct object pronounsWhere did "español" go? It was replaced — and the replacement moved to a different position in the sentence. Can you see the pattern for where it lands?
Direct object pronouns (lo / la / los / las) replace a noun and move to sit directly before the conjugated verb — even before "no". They follow the same gender and number pattern as the articles you learned in step 3.
Verbs that take infinitives
infinitive constructionsEach sentence contains two verbs. One is conjugated with a person ending; the other ends in -ar, -er, or -ir. Which is which, and what does the second verb do?
Many Spanish verbs (querer, poder, necesitar, saber) take a second verb in its infinitive form directly after them — no extra word needed. "Voy a + infinitive" is the most common way to express the near future.
Two verbs for "to be"
ser vs. estarBoth verbs translate as "to be" in English. Look at what follows each one. Can you spot what type of information triggers each verb?
"Ser" is for permanent identity — what something fundamentally is. "Estar" is for states, locations, and conditions that can change. The same adjective can combine with either: "El café es bueno" (good in general) vs. "El café está bueno" (tastes good right now).
Actions that loop back
reflexive verbsA short word appears just before the verb in each example. It changes to match the subject — "me" for I, "se" for he/she. What do you think it's doing?
Reflexive pronouns (me / te / se / nos) show the action loops back to the subject. Many everyday actions in Spanish are reflexive — waking up (despertarse), getting dressed (vestirse), introducing yourself (llamarse).
The two past tenses
preterite vs. imperfect| Tense | Pattern | Example |
|---|---|---|
| Preterite | -é, -aste, -ó | hablé (I spoke) |
| Imperfect (-ar) | -aba, -abas, -aba | hablaba (I used to speak) |
| Imperfect (-er/-ir) | -ía, -ías, -ía | comía (I used to eat) |
Both sentences talk about the past, but they use different endings. The first describes something that happened at a specific moment; the second describes something ongoing or habitual. Can you tell which is which?
Spanish has two simple past tenses: the preterite marks a completed event, and the imperfect marks an ongoing state or habit.
The compound past
haber + participleNow the verb is two words. What does the first word do? What happens to the second word when you change the subject?
"Haber" (he/has/ha/hemos/han) is the auxiliary — like English "have". The second part is the past participle: replace -ar with -ado, -er/-ir with -ido. Only the auxiliary changes for person; the participle never changes.
The mood of possibility
subjunctive mood"Hables" looks like "hablas" from step 1 — but the ending is different. Something changed it. What comes before it that might be the trigger?
The subjunctive is a second set of verb endings that appears after expressions of desire, emotion, doubt, or obligation. The vowel flips: -ar verbs use -e endings; -er/-ir verbs use -a endings. "Quiero que hables" — the speaker wants, so the listener's verb goes into subjunctive.
Impersonal "se"
passive seThere is no named subject in these sentences — no "I", "you", or "they". Who is doing the action? How does Spanish express this?
"Se" before a third-person verb creates an impersonal or passive construction — equivalent to "one does", "it is done", or the English passive. The verb agrees with the noun that follows it, not with a person.
The full picture
putting it togetherHow many grammar patterns from earlier steps can you identify in these sentences? Try naming each one.
Spanish grammar is a small number of regular patterns applied repeatedly. Once you can see those patterns at work in complex sentences, you can read, adapt, and build new sentences of your own.
