Latin Grammar Formation of the Imperfect Tense (Grammar 4A, pp. 194-96)
The Formation of the Imperfect Tense • In all verbs but sum and verbs made from sum, the imperfect tense, which is a past tense, is made with the syllable –bā–plus the normal personal endings. amābāmus habēbātis loquēbātur
Imperfect Tense:Non-Deponent endings • Here are the non-deponent endings for the imperfect: The -a- wants to be long. But remember: Vowels before final m, t and r are generally short in Latin. All vowels are short before any -nt-.
Imperfect Tense:Non-Deponent endings • Here are the deponent endings: The -a- wants to be long. But remember: Vowels before final m, t and r are generally short in Latin. All vowels are short before –nt.
First Conjugation • To form the first conjugation imperfect, add the imperfect endings to the present stem of the verb. • This is made by removing the –re from the infinitive of non-deponent verbs or the –rī from the deponent infinitive): amāre => amā- minārī => minā-
First Conjugation • Now add the endings.
2nd, 3rd, 4th, and 3rd-io • The other conjugations have a long e at the end of the stem. habeō => habē- polliceor => pollicē- dīcō => dīcē- loquor => loquē-
2nd, 3rd, 4th, and 3rd-io • 4th and 3rd-io verbs have an i before the long e. audiō => audiē- mentior => mentiē- capiō => capiē- prōgredior => prōgrediē
