All the tenses you have studied so far are called ‘indicative’: they describe an actual event, something that happens. It may have already happened (past tenses), or not happened yet (future), or if negative not happen at all, but it still deals with an actual and not a hypothetical event. These uses of veniō,-īre are all indicative:

domum vēnit (perfect indicative)

s/he came home

domum veniet (future indicative)

s/he will come home

domum nōn venit (present indicative)

s/he is not coming home
