What word or phrase does your mother always say?
Old English wyscan "to wish," from Proto-Germanic *wunskijanan (cf. Old Norse æskja, Danish ønske, Swedish önska, Middle Dutch wonscen, Dutch wensen, Old High German wunsken, German wunschen "to wish"), from PIE *wun-/*wen-/*won- "to strive after, wish, desire, be satisfied" (cf. Sanskrit vanati "he desires, loves, wins," Latin venus "love, sexual desire, loveliness," venerari "to worship;" see Venus). The noun is attested from c.1300. Wish fulfillment (1901) translates German wunscherfüllung (Freud, "Die Traumdeutung," 1900).
