Usage: Use "objectionable" to describe something that provokes reasonable criticism or moral discomfort, such as behavior deemed inappropriate by social standards. It is often confused with the stronger term "offensive," but while all objectionable things may be disliked, not everything people dislike rises to the level of being worthy of formal objection.
The word objectionable comes from combining the noun objection with the suffix -able. It entered English to describe something that is capable of being objected to or causing disapproval.
