köken: Inherited from Middle French baptesme, from Old French batesme, bapteme, baptesme (earlier batesma), a semi-learned borrowing from Ecclesiastical Latin baptisma, from Ancient Greek βάπτισμα (báptisma), and Late Latin baptismus, baptismum from Ancient Greek βαπτισμός (baptismós). Doublet of baptisme.
köken: From Middle Low German dōpe, from Old Saxon dōpi, from Proto-West Germanic *daupīni, from Proto-Germanic *daupīniz, from Proto-Indo-European *dʰewbʰ-. Doublet of doppa and djup.
baptism (a Christian sacrament, by which one is received into a church and sometimes given a name, generally involving the candidate to be anointed with or submerged in water)
köken: From Old Danish dop, borrowed from Middle Low German dōpe, dōp, from Old Saxon dōpi, from Proto-West Germanic *daupīni (“immersion”), cognate with German Taufe, also whence Danish døbe (“to baptize”) and German taufen.
From Middle High German toufe, from Old High German toufī, from Proto-West Germanic *daupīni (“dipping, immersion”). Upper German form with lack of umlaut before a labial; reinforced probably by the fact that the Central German variants clashed with Teufe, older form of Tiefe (“depth”).
