1. Present tense –AR verb conjugaions
Verbs have two forms, infinitives [in English the to form (to study)] and the conjugated form that shows who or what does the action.

2. Infinitive: I want to study now.
Quiero estudiar ahora.
Conjugated: Ana studies
Ana estudia

3. In English we use the pronouns I, you, he, she, it, we and they to show who is doing the action. In Spanish, the endings of the conjugated verb forms show who is doing the action.

4. To conjugate a verb whose infinitive ends in –AR [mirar, hablar, etc],
1) drop the –ar and
2) add the following endings:

5. I (yo) -o we (nosotros) -amos
You (tú) -as you (vosotros -áis
in Spain)
He (él) they (ellos)
She (ella) -a they (ellas) -an
You (Ud) you (Uds)

6. Hablo can only mean I speak
Hablas can only mean you speak
Hablamos can only mean we speak

7. BUT, for example:
Habla has several meanings :
he speaks
she speaks
you [Ud] speak

8. Therefore, if the subject is not known, you must indicate who is doing the action:
Él habla he speaks
Luís habla Luís speaks
Ella habla she speaks

9. Mi amigo habla
My friend speaks
El Señor Ramos habla
Señor Ramos speaks
Ud habla you speak
