Forms

tacitē (comparative tacitius, superlative tacitissimē)[1]

Etymology

It is from Latin tacitus (“silent”) + -ē.[2] The adjective is the participle of taceō (“to be silent”),[1] which de Vaan traces to Proto-Italic *tak-ē- (“to be silent”) and Proto-Indo-European *tHk-eh₁- (“to be silent”).[3] Its nearest cognate is Umbrian taçez (“tacit”), a participle.[3]

Earliest recorded meaning

Georges cites Plautus for tacitē auscultāre, “to listen in silence”;[4] Köbler dates it first from Accius.[5]

Semantic evolution

Its first sense is without a sound, silently, and then without speaking, without protest or complaint, and without publicity.[2] Cicero has tacitē rogāre, “to ask silently”,[4] and Livy describes people who would curse a man under their breath as he passed by.[4][6] From “without words” came “by implication, tacitly”: in Cicero the law tacitē dat … potestātem dēfendendī, “tacitly grants the right of self-defence”.[6] It also meant secretly, privately,[2][6] and, of a slow change, unnoticed: Ovid has tacitē lābēns annus, “the year gliding silently by”,[4] and Persius a skin turning yellow imperceptibly.[2][6] Medieval Latin kept all these senses; a 14th-century Oxford statute forbids consenting to secret meetings tacitē vel expressē, “tacitly or expressly”.[7]
