The quality or state of being alluring; attractiveness or appeal that tempts or draws others in.
From 'alluring' (present participle used as adjective) + '-ness' (suffix forming abstract nouns). The '-ness' suffix creates an abstract noun denoting the quality itself.
Adding '-ness' to an adjective is a favorite English trick, and 'alluringness' perfectly captures the ineffable quality of allure—it's not just beauty or charm, but their combined seductive power.
