Completio

Completio is a Latin noun meaning completion, fulfillment, or perfection. It derives from the verb compleo, “to fill up,” and the suffix -tio, which forms abstract nouns. In Latin texts, completio denotes the act of making something complete as well as the state of being complete or perfected.

Historically, completio appears in Classical and medieval Latin in philosophical, legal, and theological contexts. It is used to describe the completion of a process, the fulfillment of a requirement, or the final perfection of a thing. In scholastic and ecclesiastical writing, the term can appear in discussions about the completion or perfection of human faculties, a text, or a set of conditions, depending on the author's emphasis.

In modern scholarship, completio is primarily encountered in studies of Latin language and literature rather than as a standalone contemporary concept. When translated into English, the word most often yields “completion,” “fulfillment,” or “perfection,” with the exact sense dictated by the surrounding discourse. The term is typically found in analyses of classical or medieval texts rather than in current technical vocabularies.
