Introduction
Estudiar means “to study”, and this page covers exactly one thing: estudiar in the present tense. The present is the tense Spanish speakers reach for when they talk about what happens regularly, what is true in general, and what is happening right now. On this page you will find the full present table for estudiar, how the tense is formed for this verb, the situations where it is used, how it differs from the preterite, worked examples, the mistakes learners make most often, an eight-question quiz with explained answers, and answers to the questions students ask about estudiar in the present. Estudiar is the verb for studying a subject: Spanish, medicine, history. The subject is the direct object, with no preposition. For example: “Yo estudio español todos los días.” — I study Spanish every day.

Gerund: estudiando · Past participle: estudiado
The gerund is estudiando, which you use with estar to say what is happening right now: “Estoy estudiando” means the action of estudiar is in progress at this very moment. The past participle is estudiado, which you use with haber in the perfect tenses: “he estudiado” is the present perfect, used for a completed action. Keep both forms in mind as you read the examples below, because the present is only one part of how estudiar is used.
How the present of estudiar is formed
Estudiar is a regular -ar verb, so the present follows the standard pattern with no surprises. Take the stem estudi (the infinitive without its -ar ending) and add the present endings: -o for yo, -as or -es for tú, -a or -e for él/ella/Ud., -amos / -emos / -imos for nosotros, -áis for vosotros, and -an or -en for ellos/ellas/Uds.. That gives you estudio, estudias, estudia, estudiamos, estudiáis and estudian. Because the verb is regular, once you know the stem and the six endings you can produce every form without memorising a list, and the same pattern works for every other regular -ar verb you learn.
When to use the present of estudiar
The present is not a single-purpose tense. Below are the five situations where you will use estudiar in the present most often. Each one comes with a real example, so read the rule, then say the example out loud.
1. Studying a subject
Estudiar is the verb for studying a subject: Spanish, medicine, history. The subject is the direct object, with no preposition. Example: “Yo estudio español todos los días.” — I study Spanish every day.
2. Studying for an exam
Estudiar para + exam means to study for an exam. The para marks the goal of the studying. Example: “¿Tú estudias para el examen?” — Are you studying for the exam?
3. Studying at a place
Estudiar en + place means to study somewhere: at the library, at home, at university. The en marks the place. Example: “Nosotros estudiamos en la biblioteca.” — We study in the library.
4. Habits and routines
The present tense is the tense of routine. When something happens every day, every week or every morning, the present is the natural choice, and estudiar is no exception. Use time expressions such as todos los días, siempre or cada semana to make the routine explicit. Example: “Yo estudio español todos los días.” — I study Spanish every day.
5. What is happening right now
The present also describes an action in progress at this very moment. Spanish often prefers the simple present where English would use the continuous form, so a sentence with estudiar in the present can mean both “I do this” and “I am doing this now”. Context tells the listener which one you mean. Example: “Nosotros estudiamos en la biblioteca.” — We study in the library.
Present Tense vs Preterite: how to choose
The closest tense to the present is the preterite, and learners mix them up constantly. The rule is simple: the present describes habits, general truths and what is happening now, while the preterite describes one finished action in the past. The three pairs below use the same verb, so the only thing that changes is the time frame — and with it, the tense. Notice how the present sentences use words such as todos los días or siempre, while the preterite sentences use ayer or la semana pasada. Those time words are your best clue when you are choosing a tense.
Present Tense: “Yo estudio español todos los días.” — I study Spanish every day.
Preterite: “Ayer yo estudié tres horas.” — Yesterday I studied for three hours.
Todos los días describes a routine, so the present is right; ayer names one finished day, so the preterite is right.
Present Tense: “Mi hermano estudia medicina todos los días.” — My brother studies medicine every day.
Preterite: “Mi hermano estudió medicina ayer por la noche.” — My brother studied medicine last night.
Todos los días signals repetition, so the present fits; ayer por la noche names one finished evening, so the preterite fits.
Present Tense: “Yo estudio español todos los días.” — I study Spanish every day.
Preterite: “Ayer, yo estudié español todos los días.” — the same action, but finished yesterday instead of repeated as a habit.
The present sentence is true every day; the preterite sentence is true once, yesterday. That difference — routine versus one finished event — is the whole decision.
Example sentences: estudiar in the present
Read these eight sentences out loud. They cover all six persons, so by the end you will have seen every form in the table used in a real sentence. Pay attention to the words around the verb — the time expressions, the objects, the other verbs — because those are what make each sentence sound natural.
“Yo estudio español todos los días.” — I study Spanish every day.
“¿Tú estudias para el examen?” — Are you studying for the exam?
“Mi hermano estudia medicina en Madrid.” — My brother studies medicine in Madrid.
“Nosotros estudiamos en la biblioteca.” — We study in the library.
“Vosotros estudiáis historia en el instituto.” — You study history at school.
“Ellos estudian inglés por la noche.” — They study English at night.
“Yo estudio con mis amigos los sábados.” — I study with my friends on Saturdays.
“Mi padre estudia derecho por las noches.” — My father studies law at night.
Common mistakes with estudiar in the present
These are the errors learners actually make with this verb in this tense. Each one shows the wrong version, the right version, and why the correction matters.
Wrong: “Yo estudio de español.” Right: “Yo estudio español.” Why: Estudiar takes a direct object with no preposition: estudio español, not estudio de español. The de appears only in phrases such as 'estudio un curso de español', where it belongs to curso.
Wrong: “Ellos estudia inglés.” Right: “Ellos estudian inglés.” Why: Ellos needs the ellos form estudian. The singular estudia belongs with él, ella or a singular noun such as mi hermano.
Wrong: “Yo estudio tres horas ayer.” Right: “Ayer yo estudié tres horas.” Why: The present tense cannot describe a finished study session yesterday. Ayer forces the preterite, so the form must change to estudié.
Wrong: “Nosotros estudias en la biblioteca.” Right: “Nosotros estudiamos en la biblioteca.” Why: Nosotros needs estudiamos. The tú form estudias belongs with tú.
