Present Tense of
Regular –AR Verbs
An infinitive tells the meaning of a verb
without naming any subject or tense.
 There are three kinds of infinitives,

◦ Those that end in AR
◦ Those that end in IR
◦ Those that end in ER
In English
In English, most verbs have only two forms in the present
tense so subject pronouns can’t be left out.
I sing
You sing
He/She/You sing(s)
We sing
you all sing**
They/you all sing
IN SPANISH
The verb endings tells you who the subject is.
CANTO
CANTAS
CANTA
CANTAMOS
CANTAIS
CANTAN

Every verb has a stem followed by an
ending. The stem tells the verbs
meaning. An infinitive ending doesn’t
name a subject or a tense

To give the verb a subject, you
conjugate it. To conjugate a regular –ar

ending of the infinitive and add these
endings. Each ending goes with a
particular subject pronoun.

(NOSOTROS/AS)
(TU)
(VOSOTROS/AS)
as
(EL/ELLA/USTED) a
amos
áis

verb tells the subject, the subject pronoun
is normally left out. Use the subject
pronouns to add emphasis, or when it
wouldn’t otherwise be clear who the
subject is.

Do you skate a lot?
Ellos patinan. Yo nunca patino.
They skate. I never skate.
