Explanation:
* The imperfect past tense of the indicative is a frequent tense in Romance languages. It describes an action or state in the past whose time limits are not relevant, that is, a grammatical time of the past with a grammatical aspect. It is used in Spanish to express courses of past actions whose beginning and end are not specified.
* The preterite tense is used to talk about actions that took place in the past and has no relation to the present.
The past perfect simple or past tense is formed based on the root of the verb (infinitive minus -ar, -er, or -ir) and adding the following disinherities:
* Verbs of the first conjugation (ending in -ar): -é, -aste, -ó, -amos, asteis, -aron
* Verbs of the second and third conjugation (ending in -er or -ir): -í, -iste, -ió, -imos, -isteis, -ieron
