transiit

Transiit is a Latin verb form, the third-person singular perfect indicative active of transire, the verb meaning "to go across" or "to pass over." The form represents a completed action in the past and is usually translated as "he/she/it crossed" or "he/she/it has crossed." Transire itself is built from the prefix trans- meaning "across" and ire meaning "to go." The perfect is formed from the stem transi- plus the ending -it, yielding transiit.

In classical Latin, transiit is common in narrative prose and poetry to report the crossing of rivers, roads, walls, or other boundaries, as well as in metaphorical uses such as crossing from one state to another. It contrasts with transit, the present-tense form meaning "he crosses" or "it passes." The word also has related forms: the present tense transit, the passive participle transitus, and the supine transitum.

Transiit is attested in inscriptions and literary texts from antiquity through the medieval period and remains a standard form in Latin grammar references as the perfect form of transire. It is primarily encountered in studies of Latin morphology and philology, where precise tense and aspect of transire are discussed in grammatical tables and lexicons.
