Grammar Rules & Patterns
Regular -AR Verb Conjugation
Verb Stem + -aba, -abas, -aba, -ábamos, -abais, -aban
For regular verbs ending in -ar, remove the -ar ending from the infinitive to find the stem. Then, add the appropriate imperfect ending based on the subject. Note the accent on the 'a' in the nosotros form: -ábamos.
Regular -ER and -IR Verb Conjugation
Verb Stem + -ía, -ías, -ía, -íamos, -íais, -ían
For regular verbs ending in -er or -ir, remove the ending to find the stem. Then, add the appropriate imperfect ending. Note that the endings are identical for both -er and -ir verbs and all forms have an accent on the first 'i'.

Analyze the sentence: 'Cuando nosotros _________ en Madrid, _________ al Museo del Prado todos los meses.' Which verb pair correctly fills the blanks to describe a past situation and a resulting habitual action?

C.vivimos / fuimos

Challenging
Consider the verb 'saber' (to know). The preterite 'supe' means 'I found out,' while the imperfect 'sabía' means 'I knew.' Why does this change in meaning occur?
A.Because 'saber' is an irregular verb in both tenses.
B.Because the preterite marks the beginning of a state, while the imperfect describes the state itself as ongoing.
C.Because the imperfect is only used for physical descriptions, not mental states.
D.Because the meaning of verbs does not change between tenses.
Challenging
Evaluate the four sentences. Which one incorrectly uses the imperfect for an action that, by its nature, is a single, non-repeatable event?

B.La profesora nos daba mucha tarea cada noche.
