  A regular verb in Latin belongs to one of four main conjugations. A conjugation is "a class of verbs with similar inflected forms." The conjugations are identified by the last letter of the verb's present stem. The present stem can be found by omitting the - re (- rī in deponent verbs) ending from the present infinitive form. The infinitive of the first conjugation ends in -ā-re or -ā-ri (active and passive respectively): amāre, "to love", hortārī, "to exhort"; of the second conjugation by -ē-re or -ē-rī: monēre, "to warn", verērī, "to fear;" of the third conjugation by -ere, -ī: dūcere, "to lead", ūtī, "to use"; of the fourth by -ī-re, -ī-rī: audīre, "to hear", experīrī, "to attempt". The stem categories descend from Indo-European and can therefore be compared to similar conjugations in other Indo-European languages.
  
  Irregular verbs are verbs that do not follow the regular conjugations in the formation of the inflected form. Irregular verbs in Latin are esse, "to be"; velle, "to want"; ferre, "to carry"; edere, "to eat"; dare, "to give"; ire, "to go"; posse, "to be able"; fieri, "to happen"; and their compounds.
  
  There are six simple tenses in Latin (present, imperfect, future, perfect, pluperfect and future perfect), three moods (indicative, imperative and subjunctive, in addition to the infinitive, participle, gerund, gerundive and supine), three persons (first, second and third), two numbers (singular and plural), two voices (active and passive) and two aspects (perfective and imperfective). Verbs are described by four principal parts:
  
  The six simple tenses of Latin are divided into two systems: the present system, which is made up of the present, imperfect and future forms, and the perfect system, which is made up of the perfect, pluperfect and future perfect forms. Each simple tense has a set of endings corresponding to the person, number, and voice of the subject. Subject (nominative) pronouns are generally omitted for the first (I, we) and second (you) persons except for emphasis.
  
  The table below displays the common inflected endings for the indicative mood in the active voice in all six tenses. For the future tense, the first listed endings are for the first and second conjugations, and the second listed endings are for the third and fourth conjugations:
