Etymology

The verb is derived from Late Middle English nebillen, nebyll (“to peck away at (something), nibble; (figurative) to attempt to sing (a part of a song)”); further etymology uncertain, possibly from Middle Low German nibbelen (“to eat in small bites, peck”) (modern German Low German nibbeln, gnibbeln, knibbeln), possibly a variant of knabbelen, ultimately from Proto-Indo-European *gnet- (“to press”) or imitative. The noun is derived from the verb. Cognates * Middle Dutch cnibbelen (modern Dutch knibbelen (“to gnaw; to murmur”), nibbelen (“to nibble”)) * Saterland Frisian nibje (“to nibble”) * West Frisian knibbelje

A pun on the homophony of byte and bite.
