What does questionable mean?
Questionable means that something is open to doubt, challenge, or uncertainty. It is often used for claims, evidence, decisions, motives, or methods whose truth, reliability, or appropriateness is not clear. Saying that a conclusion is questionable suggests that it may be inaccurate or unjustified, but does not necessarily mean that it is false. The word can also describe conduct or choices that raise ethical or legal concerns, as in “a questionable business practice.” In everyday use, it is a clear and measured way to express suspicion while leaving room for further information. Because it describes a problem with certainty, truth, or acceptability rather than simply giving a direct verdict, questionable is especially useful in reporting, criticism, research, and discussion.

Where does questionable come from?
Questionable was formed in English from question plus the suffix -able, meaning “capable of being questioned” or “open to question.” The word question comes through Old French from Latin quaestio, a noun meaning “a seeking” or “an inquiry,” ultimately derived from quaerere, “to ask or seek.” Related English words include quest, request, and inquiry, all of which reflect the same broad tradition of asking and seeking.
