Etymology tree Middle Dutch snappen Dutch snappenbor. Low German snappenbor. English snap From Dutch snappen (“to bite; seize”) or Low German snappen (“to bite; seize”), ultimately from Proto-West Germanic *snappōn, from Proto-Germanic *snappōną (“to snap; snatch; chatter”), intensive form of *snapāną (”to snap; grab”, whence Old Norse snapa (“to get; scrounge”)), from Proto-Indo-European *snop-; compare Lithuanian snãpas (“beak, bill”). (One alternative hypothesis links the Germanic words to *snu-, an expressive root deriving words meaning “nose”, “snout”, “sniff” etc., but this is phonetically unsound.) In any case influenced by onomatopoeia; note expressions such as snip-snap, containing the formally unrelated snip. Cognate with West Frisian snappe (“to get; catch; snap”), German schnappen (“to grab”), Swedish snappa (“to snatch”). The verb is derived from the noun.
