Effici

Effici is a Latin linguistic term that refers to the present passive infinitive form of the verb efficere (also seen as efficio in some grammars). In Latin, effici means “to be brought about” or “to be effected.” It functions as a non-finite verb form used within clauses to express passive voice, particularly in purpose, result, or indirect discourse constructions. An example in spirit would be ut id efficiatur, meaning “that it may be accomplished.” The exact spelling and form can vary by edition and grammatical tradition, but the underlying sense remains “to be brought about.”

Etymology and related forms: The word derives from the Latin verb efficere, a compound of ex- “out” and facere “to do/make,” literally signaling something being brought about. This root contributes to a family of English derivatives such as effect, effective, efficiency, and efficacious. The Latin non-finite form effici is thus a linguistic stem that has carried into the Old and Modern English words through translations and scholarly usage.

Usage notes: In Latin texts, effici appears mainly in refined or formal passages and is encountered alongside related forms like efficiatur (present passive subjunctive) and efficī (as the passive infinitive in certain grammars). The form is primarily of interest to students of Latin grammar, historical linguistics, and philology, rather than to modern non-linguistic fields.
