What does "ostensible" mean?

The term "ostensible" refers to something that is represented or appears to be a certain way, often suggesting that there is a surface level truth or appearance that may not fully align with reality. It implies that there is an outward presentation or demeanor that one might initially take at face value. For example, someone might have an ostensible interest in a topic, signifying that their interest is presented externally, even if their true motivations or feelings might differ underneath. This nuanced understanding of the term can reflect on social situations, motivations, or intentions that are visible to others but not necessarily the complete picture.

The other meanings associated with the remaining options do not align with the definition of "ostensible." Hidden or concealed suggests a lack of visibility that contradicts the notion of appearance. Undeniably true implies a certainty that is not implied by "ostensible," which includes an element of ambiguity. Lastly, illogical or irrational does not connect to the concept of appearance, as it pertains more to reasoning and logic rather than how something is perceived. Consequently, the correct understanding of "ostensible" highlights its role in highlighting appearances versus underlying truths.
