Remember This
Questionable can imply doubt about truth or reliability, and in some contexts it can also hint at suspicious or dubious behavior. The root idea is that something invites questioning.
Other Forms
Note
Be careful not to confuse with 'unclear' or 'suspect' in all contexts; use 'questionable' when you want to flag doubt or controversy, rather than outright falseness. In formal writing, it often precedes a qualifier like 'at best' or 'due to limited evidence.'
