welcome

From Middle English welcome, wolcume, wulcume, wilcume, from Old English wilcuma (“a wished-for guest”; compare also wilcume (“welcome!”, interjection)), from Proto-West Germanic *willjakwemō, from Proto-Germanic *wiljakwemô (“a wished-for arrival or guest”), possibly from *wiljakwemaną (“to be welcome”), equivalent to will (“desire”) +‎ come (“comer, arrival”). The component wil- was replaced by wel- when the sense “guest” of the second component was no longer understood, likely under influence from the adverb well.
