tacit

adj

Etymology: Borrowed from late Middle French tacite, or from Latin tacitus (“that is passed over in silence, done without words, assumed as a matter of course, silent”), from tacere (“to be silent”).

1. Implied, but not made explicit, especially through silence.

   “tacit consent”

   “Our tacit treaty with Miss Maudie was that we could play on her lawn, eat her scuppernongs if we didn’t jump on the arbor, and explore her vast back lot,”

2. Not derived from formal principles of reasoning; based on induction rather than deduction.
