Etymology

The word "dated" combines "date," derived from Latin "data" (given, assigned), originally used in documents ("data Romae" = given at Rome). The suffix "-ed" forms adjectives or past tense verbs. Over time, "dated" evolved to describe things tied to a specific time, later acquiring the connotation of being outdated as societal norms shifted.
