Explanation:
In Spanish, the preterite is a grammatical tense used to describe absolute events or completed actions at a point in the past; things that took place on specific days or dates, specific times or time periods and events in a sequence. To conjugate a regular verb in preterite, we have to remove the infinitive ending (-ar, -er, -ir) and add the preterite ending depending on the pronoun. The endings are the following.
Subject -ar verbs -er and -ir verbs
Yo -é -í
Tú -aste -iste
Él, ella, usted -ó -ió
nosotros -amos -imos
vosotros -asteis -isteis
ellos, ellas, ustedes -aron -ieron
**Conjugation of irregular verbs varies.
On the other hand, the imperfect tense is used to describe habitual or continuous actions in the past, and for past actions that did not have a definite beginning or end.
To conjugate a regular verb in the imperfect tense, we have to remove the infinitive ending (-ar, -er, -ir) and add the imperfect ending depending on the pronoun. The endings are the following.
Subject -ar verbs -er and -ir verbs
Yo -aba -ía
Tú -abas -ías
Él, ella, usted -aba -ía
nosotros -ábamos -íamos
vosotros -abais -íais
ellos, ellas, ustedes -aban -ían
