Definition
In the civil law, *signare* means to seal or to affix a seal to a document. The term derives from the Latin *signum*, meaning a mark or sign, which in the legal context referred specifically to the impression made in wax or another medium to authenticate a writing. To *signare* was to perform a formal act of authentication — the equivalent of executing a document by seal in the Roman legal tradition.
The act was not merely ceremonial. In Roman legal practice, sealing a document gave it legal force and served as evidence of the parties' intent and identity. The *signum* impressed in wax was understood as the maker's mark, and the act of affixing it carried legal consequences for the validity and enforceability of the instrument.

Common Language
Modern common usage (Wiktionary): In present-day English, the word *signare* (or its derivative form *signare*) does not appear as a common English word. Wiktionary records "signare" in a distinct historical and cultural sense — a mulatto French-African woman of the island of Gorée or Saint-Louis in French Senegal during the 18th and 19th centuries, a term rooted in West African colonial social history.
Historical common usage: No standard English common usage applies; the term was never naturalized into ordinary English vocabulary.
The two meanings share no legal or linguistic connection. The West African social usage is a phonetic and cultural borrowing through French colonial contact, entirely unrelated to the Latin civil law term. Researchers encountering *signare* in historical legal sources should not associate it with the Senegalese historical usage, which belongs to colonial social history, not legal doctrine.

Why It Matters in Research
*Signare* is a term a researcher encounters in Latin-language legal sources, Roman law treatises, civil law digests, and annotated translations of the Corpus Juris Civilis. It rarely appears as a standalone headword in English legal dictionaries because English common law developed its own vocabulary for sealing instruments (see SEAL, LOCUS SIGILLI). Understanding *signare* is most practically useful when reading primary civil law materials or scholarship on the influence of Roman documentary practice on civil law jurisdictions.
The key research trap is conflation with *signare* as an act of signing by signature in the modern sense. In Roman and early civil law practice, the authenticating act was sealing — not handwritten signature — and *signare* referred to that sealing act. Reading it as equivalent to modern signature misunderstands the documentary formalities of the era.
Researchers working on the history of notarial practice, the evolution from seal to signature as the primary authenticating act, or the reception of Roman law in continental Europe will find *signare* a useful reference point for the older seal-based paradigm.

Historical Dictionary Support
Burrill's Law Dictionary provides the only shelf entry for this term in the Law Mind corpus. Burrill gives a concise but accurate treatment: *signare* means "to seal; to affix a seal," locating it squarely in the civil law tradition and grounding the definition in the etymology of *signum* (wax impression, seal, or mark).
Burrill's entry is brief and does not develop the broader procedural or evidentiary context in which *signare* operated — that is, the role of sealing in establishing instrument validity, witness attestation, and the protection of testaments. Researchers needing that fuller treatment should consult works on Roman documentary practice directly; Burrill captures the core definition but not the surrounding doctrine.
No other historical dictionaries in the Law Mind corpus provide an independent entry for *signare*, making Burrill the sole point of reference for this term on the shelf.

Jurisdictional Note
As a Latin civil law term, *signare* has no direct application in common law jurisdictions. Its relevance is confined to Roman law scholarship, civil law tradition research (particularly French, Spanish, Italian, and Louisiana legal history), and the history of notarial and documentary formalities. Louisiana legal historians may encounter the concept in the context of civil law document execution rules derived from the French and Spanish colonial periods.
