Definite and indefinite articles in Spanish

A noun is a word used to denote a person, place, thing, or idea.

In Spanish, all nouns are either masculine or feminine.

Masculine and feminine in Spanish

Determining the gender of words in Spanish is not very complicated. You may have already heard that it is enough to check the ending O for masculine or  A for feminine and that you get the word in Spanish: it works but not always!

So let’s take a closer look at how male and female are formed in Spanish, starting with the simplest!

The masculine

The masculine in Spanish is distinguished by four final letters: O, R, L and Y.

There are also some exceptions which are listed in the table below.

  • la mano, the hand
  • la foto, the pic
  • la piel, the skin
  • la ley, the law

The feminine

The construction of the feminine is a little more complex than that of the masculine, but we can summarize it in 3 main principles.

  1. If the masculine of the Spanish word ends in O, it is enough to replace the O by an A to obtain the feminine.

Ex: un amigo, a friend → una amiga, a friend

  • 2. If the masculine of the Spanish word already ends in A, we only change the article to obtain the feminine.

Ex: el periodista, a journalist → la periodista, a journalist.

  • 3. If the masculine of the Spanish word ends with a consonant, we add an A to the ending and change the article to get the feminine.

Ex: un jugador, a player → una jugadora, a player.

In this table we summarize the endings of the feminine.

  • El día, the day
  • El mapa, the map
  • El planeta, the planet
  • El tema, the subject
  • El avión, the plane

Personal pronouns Subject

We’re going to learn in this Spanish lesson online the personal pronouns subject, these ones are the most important pronouns, and the “basics” of the Spanish language. They are used in place of a noun, which describes who we are talking about or who talks about what. Thanks to the use of the pronoun, as in the English language, we will know to whom the person refers in his speech. To put it simply, here is a summary table of personal pronouns in Spanish:

learn Spanish in mexico

Note: in Spanish, the subject personal pronoun is omitted when the answer is fairly obvious.

For example, we will not say “yo voy a la tienda” but “voy a la tienda” (I’m going to the shop). If the person uses the “yo”, it will mark an insistence, generally, to make a comparison or a reproach, in the sense of “me, I go to the store (unlike you)”.

We will use little “usted” in Spanish as a pronoun

Here are some examples of use of personal pronouns subject in Spanish:

  • My name is Carlos => (yo) me llamo Carlos
  • You know the problem well => Usted conoce bien el problema
  • They don’t understand => ellos no entienden
  • We go to the store => (nosotros) vamos a la tienda.

SER in Spanish – verb to be

Note that in Spanish, there are two verbs to be:

SER, which we will focus first

and ESTAR, that we will check later

Likewise, it should be understood that SER and ESTAR are used as much as each other. There is no «first» or «second verb»: they are equivalent, mean the same thing but depending on the case and what we want to express, we will use either SER or ESTAR.

It may seem complicated right now but in reality it is very simple: just look at the question! So let’s go !

When do we use SER?

SER is used to characterize a person or an object, to describe something definitive.

We will therefore use SER in the following cases:

  • A. When indicating the origin of a person.

Soy de Madrid: I am (from) Madrid

Ana es de Argentina: Ana is (originally) from Argentina.

Jean y Manon son de Francia: Jean and Manon are (originating) from France.

  • B. When we want to indicate the nationality, religion, social class (in short, what «defines» us in civil status)

Es medico: He / She is a doctor.

Soy español y católico: I am Spanish and Catholic.

  • C. To define a thing or a person in terms of character and physique.

Esta mujer es vieja: This woman is old.

Soy rubia: I’m blonde

La mesa es cuadrada: The table is square.

El libro es azul: The book is blue.

  • D. To locate an event.

La cena es en mi casa: the dinner is at my house

La fiesta es en la calle: The party is in the street.

The conjugation of SER

The conjugation of the verb SER is irregular at almost all times!

ESTAR in Spanish – verb to be

When is ESTAR used?

  • A. To locate someone or something in space and time.

Estar will therefore be followed by an additional place, time or manner.

Luis está sentado: Luis is seated

Estoy en Sevilla: I’m in Seville

Estamos en invierno: We are in winter.

  • B. To describe temporary or accidental things: mood, health, behavior, opinion.

Estoy muy contenta: I am very happy.

Ayer, Fany estaba malo: Yesterday, Fany was sick.

Alex está pensativo: Alex is thoughtful.

Estoy de viaje: I’m traveling.

Miguel está de acuerdo conmigo: Miguel agrees with me.

  • C. To express an action taking place.

Estar then works with the progressive tense which we will study in another lesson.

Estoy leyendo: I’m reading.

Laura está corriendo: Laura is running

Present Tense in Spanish

Now that you have mastered the conjugation of the verbs ser and estar, it is time to check the most frequently used verbs in present tense.

Little reminders before you start

In Spanish, the subject is contained in the ending of the verb.

The subject pronoun is only indicated if you want to emphasize the subject itself.


Hablo → I speak

Yo hablo → me, I speak

There are 3 groups of regular verbs in Spanish:

  • verbs ending in -AR
  • verbs ending in -ER
  • verbs ending in -IR

Conjugation of verbs in -AR

The model used for this group is the verb ESTUDIAR which means to study.

Irregular Spanish verbs unclassifiable and frequently used

There are totally irregular verbs that do not fit into the sections we have seen together, for some unknown reason.

Most of these verbs are completely irregular to almost all tenses. We must therefore learn them by heart. You already know two verbs: ser and estar!

This list is not exhaustive: here you will find verbs that are really essential in texts and conversations.

Reflexive Verbs and Reflexive Pronouns in Spanish

The great advantage of this lesson is that it is very easy to understand! Indeed, the reflexive verbs are conjugated like the other verbs except that you will need to add a pronoun in front of the verb to indicate that the action is applied on the subject.

How does it work in Spanish?

Very easy, you just need to remember the pronouns and conjugate the verbs with the endings of AR, ER, IR.

Let´s check how to conjugate a reflexive verb:

For example: Bañarse- means to have a shower.

How to make a question in Spanish

Knowing how to formulate and ask a question in Spanish is essential when learning a foreign language. Our first sentences are actually often questions, we ask for clarification, information.

Learning to formulate questions in Spanish may for example allow you to: ask your way, know the time, offer or ask for help, get to know someone, ask to repeat, ask the meaning of a word.

General questions

In Spanish, questions are formed in the simplest and most direct way possible.

To ask “are you sleeping?”, We will simply say ¿Duermes? in Spanish, in other words “do you sleep?”. We just use the verb right away.

More examples:

  • Do you come to my party? ¿vienes a mi fiesta?
  • Do you want to eat pizza today? ¿quieres comer pizza hoy?
  • Is José reading a book? ¿José está leyendo un libro?
  • Do you like salsa music? ¿te gusta la música salsa?

You see how simple it is.

Now let´s check how more specific questions are made, in this case we need to use the interrogative pronouns:
