portum

Portum is the accusative singular form of the Latin noun portus, meaning harbor or haven. In classical Latin, portus denotes a harbor as a place of shelter, and portum is used when the harbor is the direct object or the destination of motion.

Morphology and usage are straightforward within the second declension. The base noun is portus (nominal form, masculine). The accusative singular is portum; the genitive plural is portuum; the dative and ablative singular are portō, while the nominative singular is portus.

In Latin usage, portum commonly appears with prepositions that indicate direction, or with verbs that take an object. Examples include portum petit ("he makes for the harbor") and navigare in portum ("to sail into the harbor"). The preposition ad can also express movement toward the harbor, as in ad portum navigare, depending on the surrounding sentence structure.

Beyond its grammatical function, portum is primarily encountered in scholarly discussions of Latin grammar and classical texts. It is not a modern English term for a contemporary place or institution, though it may appear in linguistic examples or as part of Latin-language quotations. Some authors may use Portum as a fictional or fictionalized place name in literature, but such usage is not standard and varies by work.
