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 )

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.
