Did You Know?

Like its synonyms "apparent" and "seeming," "ostensible" implies a discrepancy between what appears to be and what actually is. "Apparent" suggests appearance to unaided senses that may not be borne out by more rigorous examination ("the apparent cause of the accident"). "Seeming" implies a character in the thing being observed that gives it the appearance of something else ("the seeming simplicity of the story"). "Ostensible," which descends from the Latin word ostendere ("to show"), suggests a discrepancy between a declared or implied aim or reason and the true one.

Origin and Etymology of ostensible

French, from Latin ostensus, past participle of ostendere to show, from obs-, ob- in the way + tendere to stretch — more at ob-, thin

First Known Use: circa 1771
