Final answer:
The form of the imperfect tense is 'iba'
Step-by-step explanation:
The verb 'iba' is the form of the imperfect tense. The imperfect tense is used to talk about ongoing or habitual actions in the past. It is formed by adding specific endings to the stem of the verb. For example, in the verb 'ir' (to go), the imperfect form is 'iba' for first-person singular (I was going), while 'voy' is the present tense form.
