Sense: adjective/1

All three words describe something that does not fit a situation, but they differ in strength and context. 'Inappropriate' is the broadest term, covering social, professional, and ethical situations — a joke can be inappropriate, as can a piece of clothing or a comment. 'Unsuitable' focuses more on practicality and function: an unsuitable candidate lacks the right skills, not necessarily the right manners. 'Improper' carries a stronger sense of rule-breaking, often in formal or moral contexts — improper conduct at work might lead to discipline. 'Unacceptable' is the strongest, implying that something cannot be allowed to happen at all. For example, wearing jeans to a formal dinner is inappropriate; wearing nothing at all is unacceptable.

Etymology

LatinEnglish

From Latin 'in-' (not) + 'appropriatus', from 'ad-' (to) + 'proprius' (one's own). The word entered English around the 1600s meaning 'not made one's own,' and by the 1700s took on the modern meaning of 'not suitable or proper for the occasion.'
