Definition
The Prime Serjeant was the monarch's first, or most senior, serjeant-at-law — the lead advocate within the ancient English order of serjeants-at-law who held a formal appointment to serve the Crown. The title shifted with the sovereign: Prime Serjeant to the King when a king reigned, Prime Serjeant to the Queen during a queen's reign. The position was among the most prestigious appointments available to a practicing advocate in the English common law system before the order of serjeants-at-law fell into disuse in the nineteenth century.
The role was distinct from the Attorney General and Solicitor General. The Prime Serjeant was the Crown's foremost advocate drawn from the serjeant order specifically, while the Attorney and Solicitor General were officers of the Crown more broadly responsible for legal advice and litigation across the government. In practice, as the common law bar evolved, the distinction blurred and the Prime Serjeant's functional importance diminished.

Common Confusion
PRIME SERJEANT vs. ATTORNEY GENERAL vs. KING'S SERJEANT: Researchers occasionally conflate these titles. The King's Serjeants (plural) were a class of royal advocates appointed from the order of serjeants-at-law. The Prime Serjeant was the senior member of that class — first among the King's Serjeants, not an officer of the Attorney General's rank. The Attorney General and Solicitor General occupied a separate, ultimately more durable line of Crown legal officership. As the serjeant order declined through the nineteenth century, the Prime Serjeant's role became vestigial, while the Attorney General's office grew in prominence and survives today.

Why It Matters in Research
This is an essentially extinct title, and researchers will encounter it almost exclusively in historical English legal sources — reports, treatises, and institutional histories from roughly the sixteenth through mid-nineteenth centuries. Several navigational points are important:
First, the gender-contingent form of the title (King's vs. Queen's) is a reliable dating signal. A source referencing the "Queen's first serjeant" places the text within the reign of a queen regnant — most relevantly, the reigns of Mary I, Elizabeth I, Anne, or Victoria. The shift in title across editions of Black's Law Dictionary (1st edition says "queen's," 2nd edition says "king's") reflects nothing more than the change from Victoria's reign to Edward VII's reign between those editions.
Second, researchers working in Law Mind's corpus on the English serjeant-at-law order will find that "Prime Serjeant" appears as an honorific marker within a larger institutional structure. Understanding that structure — the order of serjeants, their coif, their exclusive audience before the Court of Common Pleas, and the Crown appointments within their ranks — is prerequisite to interpreting references to this title correctly.
Third, the term appears with variant spellings. "Serjeant" and "sergeant" are used interchangeably across historical sources, with "serjeant" being the historically dominant English legal spelling and "sergeant" more common in American usage. Search strategies in the corpus should account for both.
Fourth, the order of serjeants-at-law effectively ended in 1877 with the Judicature Acts reorganization of the English court system, after which the title became purely historical. Any source after that date using the title is either retrospective or anachronistic.

Historical Dictionary Support
The four source dictionaries are in full agreement on the substance: the Prime Serjeant is the monarch's first serjeant-at-law. The variation between editions is purely regnal.
Rapalje & Lawrence's entry is notable for appending a brief definition of the French law term "primer" (meaning "first" or "primary"), signaling that "prime" in this title carried its literal ordinal meaning — first in rank among the serjeants. Bouvier similarly treats the term briefly and without elaboration beyond the core definition, appending instead the separate entry for "primer election" (the eldest coparcener's right of first choice in partition), which shares the ordinal root but is an entirely distinct legal concept.
None of the historical dictionaries provide meaningful institutional context — they do not explain the relationship between the Prime Serjeant and the broader serjeant order, the appointment process, or the historical trajectory of the office. For that, researchers must turn to institutional histories of the English bar, particularly J.H. Baker's work on the order of serjeants.

Jurisdictional Note
The Prime Serjeant was an exclusively English institution. American law inherited elements of the serjeant tradition in name (some early American states used the title "serjeant-at-law"), but no American equivalent of the Prime Serjeant or the formal Crown serjeant appointment ever developed. References to the title in American legal sources are invariably descriptive of English practice.
