Word History

Etymology

borrowed from Medieval Latin ostensibilis "perceptible, visible, capable of demonstration," from Latin ostensus, variant of ostentus, past participle of ostendere "to hold out for inspection, show, make clear by one's actions, demonstrate" (from os-, assimilated variant of obs-, variant of ob- "toward, facing, against" + tendere "to extend outward, stretch, spread out") + -bilis "capable (of acting) or worthy (of being acted upon)" — more at ob-, tender entry 3, -able

Note: Scattered attestations of the Latin word, usually in the form ostensible as a predicate adjective, can be found from Duns Scotus to the eighteenth century. The Oxford English Dictionary, third edition, attributes the English word to French, though among vernaculars ostensible is more common in Italian in the seventeenth and eighteenth centuries.
