2. Principal parts of verbs
Most Latin verbs have 4 principal parts. Amō, amāre, amāvī, amātus
1st Principal part – amō Present tense-1st person sing. “I love” or “I am loving”
2nd Principal part – amāre Infinitive. In English: “to + verb”. Example: “to love”
The infinitive ending indicates the conjugation (1-4) of the verb:
1st-āre nd-ēre rd-ere th – īre
The infinitive gives you the present stem of the verb. Drop the -re to get the present stem.
Present tense, imperfect tense & future tense are all built on the present stem.
3rd Principal part-amāvī Perfect tense,1st person sing. “ I loved” or “I have loved”
The 3rd Principal Part gives you the perfect stem. Drop the -ī to get the perfect stem.
The perfect, pluperfect and future perfect tenses are built on the perfect stem of the verb.
4th Principal part – amātus
Perfect passive participle, which is an adjective usually translated “having been ____ed”. Example: “having been loved”.
