(alt. 'nibble') [from v. 'nibble' by analogy with 'bite' => 'byte']
n. Four bits; one hex digit;
a half-byte. Though 'byte' is now techspeak, this useful relative
is still jargon.
Compare byte, crumb, tayste,
dynner; see also bit, nickle, deckle. Apparently
this spelling is uncommon in Commonwealth Hackish, as British
orthography suggests the pronunciation /ni:'bl/.
