What does bailiwick mean?
A bailiwick originally denoted the district or jurisdiction under the authority of a bailiff, a royal or judicial officer in medieval England. The word combines 'bail', from the Old French for a custodian or governor, with 'wick', from the Old English term for a settlement, ultimately tracing back to the Latin vicus. In contemporary English, however, the literal territorial meaning has largely given way to a figurative one: a person's bailiwick is their particular sphere of knowledge, skill, or responsibility. Saying that tax law falls outside one's bailiwick signals, with a touch of formality or dry humor, that the subject lies beyond one's expertise. The original sense endures mainly in official contexts, most famously in the Bailiwicks of Jersey and Guernsey, self-governing Crown dependencies in the Channel Islands. The word remains useful precisely because it conveys scope and boundary of competence in a single elegant term.

"The Bailiwick of Guernsey is a Crown dependency with its own laws and courts."
The plural is rare and typically appears only when referring to multiple historical jurisdictions, such as the Channel Island bailiwicks.
"The two bailiwicks of Jersey and Guernsey each maintain their own legal systems."
"Bailiwick" literally means a bailiff's village — the second half comes from the same Latin root as "village" itself.

Etymology of bailiwick
Bailiwick derives from Middle English, combining 'bail' — from the Old French 'baillif' (bailiff), ultimately from Latin 'bajulus', a carrier or overseer — with 'wick', from Old English 'wic', a dwelling or village borrowed from the Latin 'vicus'. It thus literally meant the village or territory governed by a bailiff. The term was established in English by the late medieval period and appears in legal usage describing jurisdictions such as those of Jersey and Guernsey.
How bailiwick is actually used
In modern usage, the figurative sense — someone's domain of expertise or concern — dominates almost entirely, especially in American English. The term carries a mildly formal or slightly old-fashioned flavor and is often used in negative constructions ('that's outside my bailiwick'). The literal legal-geographic sense survives chiefly in official names like the Channel Islands' bailiwicks.
