In a manner showing deep sadness and emotional devastation; with evident heartbreak or despair.
From 'heartbroken' (adjective) + '-ly' (Old English adverbial suffix). Combines the past participle of 'heartbreak' with the adverbial marker to describe how something is done with sadness.
Adverbs ending in '-ly' are sometimes criticized as weak writing, but 'heartbrokenly' captures something unique—a way of moving through the world when your heart is broken, which a single adjective can't fully express.
