Definition
A brevet is a government-issued commission or warrant conferring a right, rank, or privilege on a named individual, without fully conveying the benefits ordinarily attached to that status. The term carries two distinct legal meanings depending on jurisdictional context:
1. American and Military Law. A commission by which a military officer is elevated to the next higher rank in title and precedence, but without a corresponding increase in pay or command authority. A brevet promotion was honorary in character — recognizing distinguished service or merit — while leaving the officer's actual position, duties, and compensation unchanged. The rank was real for purposes of seniority in certain ceremonial or administrative contexts, but it did not entitle the holder to exercise the authority or draw the pay of the higher grade.
2. French Law. A warrant or privilege granted by the government to a private person, authorizing that individual to enjoy a special benefit or exercise an exclusive right. The most significant application was the brevet d'invention — a patent for an invention — which functioned as the French legal analog to the English letters patent. More broadly, a brevet in French administrative law was any formal governmental authorization conferring a personal entitlement.

Common Language
Modern common usage (Wiktionary): A military document entitling a commissioned officer to hold a higher rank temporarily without an increase in pay; also, in French usage, a government warrant granting a privilege, title, or dignity; colloquially, any mark or seal of recognition.
Historical common usage (Webster's 1913): A warrant from the government granting a privilege, title, or dignity (French usage); a commission giving an officer higher rank than that for which he receives pay; an honorary promotion.
The common and legal definitions align closely, but the gap that matters to researchers is precision around the word "temporarily." Common usage, including Wiktionary, frames brevet rank as inherently temporary. Historically, brevet commissions were not always temporary in a fixed-term sense — they were permanent awards of honorary rank that simply lacked pay and command equivalence. Treating brevet as a purely temporary designation can cause misreading of military records and legal disputes over seniority.

Common Confusion
Brevet rank is frequently confused with a full commission or a field promotion. The critical distinction is that a full commission carries both the title and the entitlements — pay, command authority, and precedence — while a brevet commission carries the title but withholds the entitlements. In historical military records, an officer listed at a brevet grade may have had no actual authority over officers of equivalent substantive rank. Researchers reading pension records, court-martial proceedings, or seniority disputes must identify whether a rank reference is brevet or substantive before drawing conclusions about pay, authority, or status.
In French legal contexts, brevet should not be conflated with a general royal grant or letters patent in the English sense. The brevet d'invention was the specific French patent instrument; other brevets authorized different kinds of individual privilege. The word alone, without a qualifying noun, may refer to any of these instruments.

Recognized Forms
/SUBTYPES
Brevet d'invention: The French patent for an invention; the primary vehicle by which inventors secured exclusive rights under French law. Functionally parallel to English letters patent for inventions.
Brevet rank (military): The honorary grade conferred by brevet commission. Distinct from substantive rank (the officer's actual pay grade) and from field promotion (a full elevation in rank conferred in active operational circumstances).

Why It Matters in Research
Researchers will encounter brevet most often in two distinct documentary contexts, and conflating them produces errors.
In American military law materials, the term saturates records from the Civil War era and earlier. Brevet commissions were awarded extensively during and after the Civil War, creating layers of dual rank — officers held a substantive grade for pay purposes and a brevet grade for seniority purposes — that generated substantial litigation. Seniority disputes, court of claims filings, and pension board decisions all turned on whether a given reference was to brevet or substantive rank. Bouvier's cites 14 Wall. 552 in this context, which researchers should note as a real doctrinal reference point for the American legal treatment of brevet pay rights. When reading any military legal record from the 1860s–1890s, assume the rank designation may be brevet until verified otherwise.
In French law sources, brevet appears as a general category covering multiple kinds of governmental privilege. Historical French legal dictionaries and treatises treat it as an administrative law instrument. Researchers using French-language sources or tracing the history of patent law internationally will need to distinguish brevet d'invention from other brevet instruments. Burrill's entry situates brevet in old French law as equivalent to letters patent from the crown, which connects the term to the broader history of monopoly grants and royal privilege — relevant for researchers working on the history of intellectual property or trade regulation.
The term is nearly absent from modern American statutory and case law in either sense. Military promotions are now governed by detailed statutory schemes that make the honorary-rank-without-pay structure obsolete. Brevet as a live legal term is therefore a signal of historical material — its presence in a source is itself an indicator of era and jurisdiction.

Historical Dictionary Support
The four source dictionaries present a consistent and complementary picture. Black's (both editions) and Bouvier's agree on the two-meaning structure — American military law and French law — with nearly identical language. Bouvier's adds the citation to 14 Wall. 552, giving the American military definition a case-law anchor that the other dictionaries lack. Burrill's focuses on the French law dimension, situating brevet as letters patent from the crown in old French practice, and gestures toward its connection to the broader medieval and early modern grant tradition.
None of the historical sources address the extent of Civil War–era brevet inflation, which is the most practically significant context for American legal researchers. They also do not address the question of whether brevet rank affected an officer's right to vote on courts-martial or exercise command — issues that generated real litigation — beyond the pay question. For these dimensions, researchers must move from the dictionaries to the military legal treatises and reported cases of the period.
The historical dictionaries are in agreement that brevet confers title without full entitlement. There is no meaningful divergence among them on doctrine, only difference in emphasis and detail.

Jurisdictional Note
The military law meaning is specific to the American (and by parallel development, British) armed forces and has no current operational significance in modern U.S. military law. The French law meaning is historically specific to French administrative and patent law and has no direct analog in current American doctrine. Researchers working in comparative law or legal history should treat the two meanings as jurisdictionally segregated and not assume that either imports meaning into the other's context.
