dēcīdō (present infinitive dēcīdere, perfect active dēcīdī, supine dēcīsum); third conjugation[1]
Etymology
It is from Latin dē- + caedō (“to cut”), with the vowel weakened in the compound.[2][3][1] The verb is inherited from Proto-Italic *kaid-e/o-, inherited from Proto-Indo-European *keh₂id- (“to strike, cut”).[4]
Earliest recorded meaning
It is found from Plautus onwards,[5] who uses it of cutting off a neck and, figuratively, of cutting short a trick.[2][6]
Semantic evolution
It meant to cut off, as Cato's olive cuttings and Tacitus' ears, and to reduce by cutting, as Horace's “humbled with clipped wings”.[2][3] It meant to mark out by notches, and in law to flog thoroughly.[2]
Figuratively it meant to settle or decide a matter, and with cum to come to terms with someone, as Cicero's settlement with Chrysogonus, damnum decidere was to agree on the penalty.[2] English decide came from it through Old French in the late 14th century, first “to settle a dispute”.[7]
