What does ostensible mean?
Ostensible means that something is presented as true, genuine, or intended, without asserting that it actually is. It is commonly used before words such as reason, purpose, claim, difference, or advantage: an “ostensible reason” is the reason offered to others, but it may not be the real or complete explanation. The word often carries a skeptical or mildly critical implication, suggesting that appearance and reality may differ. Nevertheless, it can also be used relatively neutrally, especially when describing a surface impression. Its close adverb, ostensibly, is especially frequent in formal English: something done ostensibly for one reason may actually have another. Ostensible is useful when discussing the difference between what is shown, claimed, or outwardly intended and what can be established as genuine.
adjectiveApparently true or genuine; presented as being true or as one's real intention, though the claim may not be accurate.
- Appearing to be true, genuine, or valid, whether or not the appearance is accurate.
- Intended, supposed, or claimed as one's real purpose or reason.
"Her ostensible reason for resigning was to spend more time with her family."
"The agreement was reached on ostensibly neutral terms, though both sides had clear preferences."
"His ostensible interest in the project seemed to be chiefly a way of spending time with the research team."
From the Latin for “to show”: ostensible marks what is put forward for others to see, not necessarily what is actually true.

Where does ostensible come from?
Ostensible entered English in the early 17th century from Latin ostensibilis, meaning “capable of being shown” or “that may be displayed.” It was formed from ostendere, “to show” or “to present,” which combines the prefix ex- (“out”) with tendere (“to stretch”). English cognates including ostend, ostentation, and ostentatious preserve the same Latin root, although their meanings have developed in different directions.
