Form the Imperfect-Tense: Conjugations 1 and 2

(Cf. Wheelock 5)

LatinPraxis Index



Form the imperfect indicative active for first and second conjugations in just two steps.


STEP 1: Get the present stem of the verb by removing the final -RE of the infinitive (the second principal part).



Principal Parts:



amô, amâre, amâvî, amâtum



moneô, monêre, monuî, monitum



STEP 2: Add -bam, -bâs, -bat, -bâmus, -bâtis, -bant.



amâbam, amâbâs, amâbat, amâbâmus, amâbâtis, amâbant


monêbam, monêbâs, monêbat, monêbâmus, monêbâtis, monêbant




The six personal endings retain their meanings:

amâbam = I used to love

amâbâmus = we used to love

amâbâs = you used to love

amâbâtis = you (pl) used to love

amâbat = he / she / it used to love

amâbant = they used to love



You will be able to derive the following imperfect forms:

vocâbam, vocâbâs, vocâbat, vocâbâmus, vocâbâtis, vocâbant

conservâbam, conservâbâs, conservâbat, conservâbâmus, conservâbâtis, conservâbant

laudâbam, laudâbâs, laudâbat, laudâbâmus, laudâbâtis, laudâbant

errâbam, errâbâs, errâbat, errâbâmus, errâbâtis, errâbant

dabam, dabâs, dabat, dabâmus, dabâtis, dabant

côgitâbam, côgitâbâs, côgitâbat, côgitâbâmus, côgitâbâtis, côgitâbant

terrêbam, terrêbâs, terrêbat, terrêbâmus, terrêbâtis, terrêbant

valêbam, valêbâs, valêbat, valêbâmus, valêbâtis, valêbant

vidêbam, vidêbâs, vidêbat, vidêbâmus, vidêbâtis, vidêbant

habêbam, habêbâs, habêbat, habêbâmus, habêbâtis, habêbant


The clue for the imperfect tense of the first and second conjugations is

-BA- /-BÂ-

immediately preceding the personal ending.
