What's the "een" in Halloween?
late 15c., from Middle French élégant (15c.), from Latin elegantem (nominative elegans) "choice, fine, tasteful," collateral form of present participle of eligere "select with care, choose." Elegans was originally a term of reproach, "dainty, fastidious;" the notion of "tastefully refined" emerged in classical Latin. Related: Elegantly.
