* -er verbs: -ía, -ías, -ía, -íamos, -íais, -ían
* -ir verbs: -ía, -ías, -ía, -íamos, -íais, -ían
* Irregular Verbs: These have their own endings and require memorization.

Important Notes:
* The imperfect tense is often used in conjunction with the preterite tense (the simple past) to narrate events in the past.
* The imperfect tense is not used to express completed actions in the past. For that, you would use the preterite tense.
