Word Origin
The phrase combines the verb 'be' (from Old English 'bēon') and 'disappointed' (past participle of 'disappoint', from Middle French 'desappointer', meaning 'to remove from office' or 'to frustrate'). The modern sense of feeling let down emerged in the 17th century.
Usage Notes
The phrase is commonly followed by 'in' (for people) or 'with' (for things). It is often used in past tense to describe a completed feeling of disappointment.
