In a manner that shows attachment, affection, or emotional connection; with devoted closeness.
From attached (past participle of attach, meaning emotionally devoted) + '-ly' (adverb suffix), creating an adverb describing how an attached person acts.
This is a genuinely rare word because we don't often need an adverb form of 'attached'—we might say someone 'clung attachedly' but modern English usually just says 'clung closely' or 'clung with devotion,' showing how words can fade when we find cleaner alternatives.
