  2. Passive, amor, amārī , amātus .

Second Conjugation:—

  2. Passive, audior , audīrī , audītus .
  3. Present Stem audī-, Perfect Stem audīv-, Supine Stem audīt-.

a. In many verbs the principal parts take forms belonging to two or more different conjugations (cf. § 189):—

  1. 1, 2, domō , domāre , domuī , domitum, subdue.
  2. 2, 3, maneō , manēre , mānsī , mānsum, remain.
  3. 3, 4, petō , petĕre , petīvī , petītum, seek.

Such verbs are referred to the conjugation to which the Present sten conforms.
