Latin 1st Conjugation Verbs

Learn How to Conjugate Latin 1st Conjugation Verbs.

There are four (4) conjugations of Latin verbs that you need to learn to read or translate Latin. In addition to the verbs of the 4 regular conjugations, there are also several irregular verbs.

[See, for instance, the conjugation of sum. ]

The Latin 1st conjugation verbs, like the Latin 1st declension nouns, are marked by an "a" as in amare. Noting this "a" (a thematic vowel) should help you to distinguish verbs of the first conjugation from those of the second, third, or fourth conjugations.

Amare = To Love

The infinitive (which we translate as "to ...") ending for the first conjugation is "-are." Note that there is no separate word "to". The infinitive includes the sense of "to" within it. One of the difficulties of Latin is learning that there is often not a neat, one-to-one correspondence between words in English and Latin. The infinitive of the 1st conjugation verb. e.g., amare, translates into English as "to love".

The 4 principal parts of a 1st conjugation verb have the following endings: -o, -are, -avi, -atus. A typical verb is laudo 'praise', so its principal parts are:

  • laudo
  • laudare
  • laudavi
  • laudatus.
