The Jargon File (version 4.4.7, 29 Dec 2003):

nybble /nib'l/, nibble, n. [from v. nibble by analogy with ?bite? ? ?byte?] Four bits; one hex digit; a half-byte. Though ?byte? is now techspeak, this useful relative is still jargon. Compare byte; see also bit. The more mundane spelling ? nibble? is also commonly used. Apparently the ?nybble? spelling is uncommon in Commonwealth Hackish, as British orthography would suggest the pronunciation /ni:'bl/. Following ?bit?, ?byte? and ?nybble? there have been quite a few analogical attempts to construct unambiguous terms for bit blocks of other sizes. All of these are strictly jargon, not techspeak, and not very common jargon at that (most hackers would recognize them in context but not use them spontaneously). We collect them here for reference together with the ambiguous techspeak terms ?word?, ?half-word?, ?double word?, and ?quad? or quad word; some (indicated) have substantial information separate entries. +-------------------------------------------------------------------------+ |2 |crumb, quad, quarter, tayste, tydbit, morsel | |bits: | | |------+------------------------------------------------------------------| |4 |nybble | |bits: | | |------+------------------------------------------------------------------| |5 |nickle | |bits: | | |------+------------------------------------------------------------------| |10 |deckle | |bits: | | |------+------------------------------------------------------------------| |16 |playte, chawmp (on a 32-bit machine), word (on a 16-bit | |bits: |machine), half-word (on a 32-bit machine). | |------+------------------------------------------------------------------| |18 |chawmp (on a 36-bit machine), half-word (on a 36-bit machine) | |bits: | | |------+------------------------------------------------------------------| |32 |dynner, gawble (on a 32-bit machine), word (on a 32-bit | |bits: |machine), longword (on a 16-bit machine). | |------+------------------------------------------------------------------| |36 |word (on a 36-bit machine) | |bits: | | |------+------------------------------------------------------------------| |48 |gawble (under circumstances that remain obscure) | |bits: | | |------+------------------------------------------------------------------| |64 |double word (on a 32-bit machine) quad (on a 16-bit machine) | |bits: | | |------+------------------------------------------------------------------| |128 |quad (on a 32-bit machine) | |bits: | | +-------------------------------------------------------------------------+ The fundamental motivation for most of these jargon terms (aside from the normal hackerly enjoyment of punning wordplay) is the extreme ambiguity of the term word and its derivatives.
The Free On-line Dictionary of Computing (30 December 2018):

nibble nybble /nib'l/ (US "nybble", by analogy with "bite" -> "byte") Half a byte. Since a byte is nearly always eight bits, a nibble is nearly always four bits (and can therefore be represented by one hex digit). Other size nibbles have existed, for example the BBC Microcomputer disk file system used eleven bit sector numbers which were described as one byte (eight bits) and a nibble (three bits). Compare crumb, tayste, dynner; see also bit, nickle, deckle. The spelling "nybble" is uncommon in Commonwealth Hackish as British orthography suggests the pronunciation /ni:'bl/. (1997-12-03)
