Insincere

Adjective · /ˌɪn.sɪnˈsɪər/

Definition

Not expressing genuine feelings; saying or doing something without meaning it; not honest or truthful in what one expresses.

Origin

From in- (not) + sincere, from Latin sincerus (pure, whole, genuine). The etymology of sincerus is debated: possibly from semel (once) + cera (wax), suggesting honey without adulteration; or from sem- (one) + root of secare (to cut), meaning of one origin. Used in English from the mid-17th century.
