Conjugating Infinitives

Spanish I

By: Candice Gregory

Introduction:

Before you can learn how to conjugate ar, ir, and er verbs you have to know your Spanish Subject Pronouns.

Singular Subject Pronouns:

  • Yo (I)
  • (you)
  • Él, ella, ud. (He, She, You)

Plural Subject Pronouns:

  • Nosotros (we)
  • Vosotros (ya'll)
  • Ellos, Ellas, uds. (they)

How do you Conjugate AR verbs?

To give the verb a subject, you conjugate it.


For Example:


  • Cantar- to sing


To Conjugate an AR verb in present tense, you first must drop the -ar ending of the infinitive.


  • Cant__


Now look back at your Spanish Subject Pronouns.


Singular Subject Pronouns:

  • Yo (I)
  • (you)
  • Él, ella, Ud. (he, she, you)


Plural Subject Pronouns:

  • Nosotros (we)
  • Vosotros (ya'll)
  • Ellos, ellas, Uds. (they)


After dropping the -ar ending to the infinitive you add different endings. Each ending goes with a particular Subject Pronoun.


Singular Subject Pronouns:

  • Yo- canto
  • Tú-cantas
  • Él, ella, Ud.- canta


Plural Subject Pronouns:

  • Nosotros- cantamos
  • Vosotros- cantáis
  • Ellos, Ellas, Uds.- cantan

How do you conjugate ER verbs?

Conjugating -er verbs is very similar to conjugating -ar verbs.


For Example:


  • Comer- to eat


To Conjugate an ER verb in present tense, you first must drop the -er ending of the infinitive. Similar so far?


  • Com__


Remember to look back at your Spanish Subject Pronouns.


Singular Subject Pronouns:

  • Yo (I)
  • (you)
  • Él, ella, Ud. (he, she, you)


Plural Subject Pronouns:

  • Nosotros (we)
  • Vosotros (ya'll)
  • Ellos, ellas, Uds. (they)


Now using your knowledge about Spanish Subject Pronouns and the -ar conjugation done in the first slide. How would you conjugate comer?


Singular Subject Pronouns:

  • Yo- Como
  • Tú- Comes
  • Él, ella, Ud.- Come


Plural Subject Pronouns:

  • Nosotros- Comemos
  • Vosotros- Coméis
  • Ellos, ellas, Uds.- Comen


Do you notice the difference? In conjugating -ar ending infinitives, you use a.

Example: Tú- Cantas


Whereas when you are conjugating -er ending infinitives you use e.

Example: Tú- Comes

How do you Conjugate IR verbs?

Conjugating -ir is similar to conjugating -ar and -er verbs but it is also very different.


For Example:



  • Escribir- to write letters



Remember to drop your -ir ending!



  • Escrib__



Also remember to look back at your Spanish Subject Pronouns!


Singular Subject Pronouns:

  • Yo (I)
  • (you)
  • Él, ella, Ud. (he, she, you)

Plural Subject Pronouns:
  • Nosotros (we)
  • Vosotros (ya'll)
  • Ellos, ellas, Uds. (they)



After dropping the -ir ending to the infinitive you add different endings. Each ending goes with a particular Subject Pronoun. Similar So far? Well it is about to get kind of tricky.


Singular Subject Pronouns:

  • Yo- Escribo
  • Tú- Escribes
  • Él, ella, Ud.- Escribe

Plural Subject Pronouns:
  • Nosotros- Escribimos
  • Vosotros- Escribís
  • Ellos, ellas, Uds.- Escriben



Do you see where it is different and where it is the same? For -ir verbs you use e mostly, just like -er verbs! Easy? Well wait till you get to Nosotros (we) and Vosotros (ya'll). Instead of using e you will just simply use i.

For Example: Tú- Escribes /Nosotros- Escribimos


For Example: Tú- Comes /Nosotros- Comemos
