In a way that shows you are unhappy or not satisfied with something.
From discontented + -ly (Old English adverb-forming suffix). The adverb form describes the manner in which someone acts or speaks when feeling dissatisfied.
When you say someone sighed 'discontentedly,' you're describing not just a sigh, but a whole mood—it's more vivid than just 'sadly' because it specifically captures the frustration of not getting what you want.
