In an attractive, tempting, or seductive manner; in a way that appeals to or attracts.
From 'allure' + '-ing' (present participle adjective) + '-ly' (adverb suffix). The '-ly' transforms the adjective 'alluring' into an adverb describing how something is done.
Adverbs like 'alluringly' let writers describe not just the thing itself but how it acts—'she smiled alluringly' is far more evocative than 'she smiled attractively,' suggesting intentional seduction.
