Definition
An archaic Law French term meaning "it shall be lawful." Used in older legal instruments and pleadings to introduce a permissive or enabling clause — that is, language granting express authorization for a party to take a particular action. The related form *lirroit* carries the conditional or subjunctive sense: "it should be lawful" or "it would be lawful."
Common Language
Modern common usage (Wiktionary): No entry. The term does not appear in general modern English.
Historical common usage (Webster's 1913): No entry. The term was confined to legal and scribal usage even at its period of currency.
LIRRA belongs entirely to the technical vocabulary of Law French and has no meaningful life outside historical legal instruments. There is no gap between common and legal meaning to navigate — the term simply has no common existence.
Common Confusion
LIRRA and LIRROIT are grammatically distinct forms and should not be treated as interchangeable. LIRRA states permission as a future certainty ("it shall be lawful"), functioning as a grant or declaration. LIRROIT introduces permission conditionally or hypothetically ("it should be lawful"), functioning more as a qualification or contingent authorization. In transcribing or interpreting historical documents, collapsing these forms loses the modal distinction the original drafter likely intended.
Why It Matters in Research
Researchers encountering LIRRA will almost certainly meet it in one context only: the transcription or analysis of medieval and early modern English legal instruments — charters, writs, licenses, patents, and pleading rolls written wholly or partly in Law French. The term functions as a signal word marking the permissive operative clause, the point in a document where authority is actually conferred. Identifying it correctly matters because permissive clauses and mandatory clauses carry different legal weight, and misreading an enabling term as something else can distort the interpretation of the instrument's scope.
Law French was the dominant language of English legal practice from roughly the Norman Conquest through the late seventeenth century, when statutes finally mandated English in pleadings. Documents from this period frequently mix Latin, Law French, and Middle English, and the same concept may appear in any of the three languages depending on the drafter, the court, and the period. LIRRA is the Law French form; researchers working across documents may encounter the Latin *liceat* or *licebit* performing the same function. Recognizing the equivalence across languages is essential for accurate comparative reading.
No modern doctrinal significance attaches to LIRRA itself. Its value is purely philological and historical: it is a reading tool, not a living legal concept. Researchers should be cautious about older secondary sources that use Law French terms without glossing them — the assumption of familiarity was common in nineteenth-century legal scholarship and is no longer warranted.
Historical Dictionary Support
Burrill's Law Dictionary is the sole historical dictionary source covering this term, and its entry is characteristically economical: "L. Fr. It shall be lawful. Lirroit; it should be lawful. Kelham. L. Fr. Dict." Burrill credits Kelham's Law French Dictionary, which remains a primary reference for Law French vocabulary and is the appropriate source for deeper philological inquiry into this term's usage and variant spellings.
Burrill's entry does the minimum necessary work — it translates both forms and attributes the source — without providing documentary examples or contextual usage. This is a limitation. No other major historical legal dictionary in the Law Mind corpus (Black's, Bouvier's, Tomlin's, Jacob's) appears to carry an independent entry for LIRRA, which confirms that by the time those dictionaries were compiled, the term had receded entirely from active legal usage and into antiquarian reference.
