Definition of Intimate and Discreet
This adjective can mean very friendly, or very personal or private. The original spelling was intime, from French, from Latin intimus “innermost,” from intus “within.” The related verb intimate means to hint or suggest. Intimate is also a noun meaning a close friend or associate.
Discreet means on the down low, under the radar, careful, but discrete means individual or detached. They come from the same ultimate source, the Latin discrētus, for separated or distinct, but discreet has taken its own advice and quietly gone its separate way.
