Pronunciation
Forms
committō (present infinitive committere, perfect active commīsī, supine commissum); third conjugation[1]
Etymology
It is from Latin con- (“together”) + mittō (“to send, let go”).[2][1] The verb mittō is inherited from Proto-Italic *meit-e/o-, inherited from Proto-Indo-European *m(e)ith₂- (“to exchange, remove”), the meaning having developed from “exchange” to “give” and “let go, send”.[3] A form ⟨cosmittere⟩ reported by Festus is not reliable enough for an etymology.[3][2]
Earliest recorded meaning
The OLD's earliest citation is Pacuvius, of a monster put together clumsily.[2] Köbler dates Pacuvius 220–130 BC.[4]
Semantic evolution
Its literal sense was to bring together, join, make continuous, construct and attach.[2] From bringing forces together it meant to join battle (proelium committere), to set people against each other and to match them in a contest.[2][1] It also meant to begin or carry on something, to entrust or commit something to someone, and to do something wrong, to commit a crime.[1][5]
It survives in Italian commettere and Spanish cometer.[1] English commit meant at first “give in charge, entrust”, in the late 14th century.[6]
