restrained
UK: rɪˈstreɪnd | US: rɪˈstreɪnd
adj. controlled or limited in behavior, expression, or style
adj. held back or kept in check
vt. (past tense of restrain) to prevent someone or something from acting freely
The word restrained originates from the Latin restringere (to bind back), combining re- (back) and stringere (to draw tight). The morpheme strain evolved from Old French estreindre (to press tightly), reflecting physical or emotional control. The suffix -ed marks it as a past participle, implying a state of being held back. The logic traces from literal binding to metaphorical self-control.
