Preterite - ar verbs
Let's consider the preterite tense of a regular -ar verb. To determine the correct forms of a verb, we start with its infinitive form. The infinitive form of the verb meaning (to speak) in Spanish is (hablar).
Now we take off the -ar ending:
hablar - ar = habl
Now we add on one of the preterite tense endings. The ending chosen will depend upon the gender of the subject and whether it is singular or plural.
|Ud./ él/ ella||ó|
|Uds./ ellos/ ellas||aron|
(formal), Nosotros = We (males/mixed group), Nosotras = We (females), Ellos
= They (males/mixed group), Ellas = They(females), Ustedes = You (plural)
