Etymology

Origin of tacit

First recorded in 1595–1605; from Latin tacitus “silent,” past participle of tacēre “to be silent” (cognate with Gothic thahan; akin to Old Norse thegja )

Explanation

Something tacit is implied or understood without question. Holding hands might be a tacit acknowledgment that a boy and girl are dating. The adjective tacit refers to information that is understood without needing to acknowledge it. For example, since we know that the sky is blue, that kind of assumption is tacit. Lawyers talk about "tacit agreements," where parties give their silent consent and raise no objections.
