Definition
adj. not connected or associated
adj. lacking a logical or causal relation
Structure
un <not>relate <connect>ed <adjective suffix>
Etymology
The word "unrelated" combines the prefix "un-" (Old English "un-," meaning "not") with the verb "relate" (from Latin "relatus," past participle of "referre," meaning "to bring back or connect"). The suffix "-ed" turns it into an adjective. The term evolved to describe things lacking connection or association, preserving the logical negation of "relate."
