Definition
An obsolete Law French term meaning favor, partiality, or association. In its legal historical context, acoigne referred to a relationship of familiarity or partisan connection — the kind of favoritism or bias that might disqualify a person from serving in an impartial capacity, such as on a jury or in an adjudicative role. The term carries the sense of improper closeness or confederacy with one of the parties to a proceeding.
Common Confusion
Acoigne should not be confused with modern terms like bias, partiality, or conflict of interest, though it gestures toward the same underlying concern. Those modern concepts carry developed doctrinal frameworks; acoigne is purely a historical term with no surviving procedural life. Researchers who encounter it in old records should resist mapping it directly onto contemporary disqualification doctrine without accounting for the very different procedural context in which it appeared.
Why It Matters in Research
Acoigne belongs to the specialized vocabulary of Law French that saturates medieval and early modern English legal records — plea rolls, year books, and early treatise literature. Researchers working in these sources need to recognize it as a term of challenge or objection, likely appearing in contexts where a party sought to disqualify a juror or officer on grounds of partiality or association with the opposing side.
The term is rare even by Law French standards. Its appearance in a source should prompt attention to the surrounding procedural context: who is being challenged, on what grounds, and what remedy or consequence followed. Because the word has no surviving common law descendant and no modern statutory analog, it functions purely as a historical marker. Do not expect to find it in post-seventeenth-century sources.
The single definitional gloss — "favor; association" — is thin, and Kelham's Law French glossary (the source Burrill draws on) is the natural next stop for any researcher needing fuller linguistic context. Robert Kelham's A Dictionary of the Norman or Old French Language (1779) is the authority Burrill cites here and remains a primary resource for Law French vocabulary in English legal records.
Corpus researchers should also be alert to variant spellings. Law French terms were recorded inconsistently, and acoigne may appear in manuscripts under alternate forms. Searching only the normalized spelling will miss instances.
Historical Dictionary Support
Burrill's entry is minimal: "L. Fr. Favor; association. Kelham." This is characteristic of Burrill's treatment of rare Law French terms — he preserves the term and its gloss but does not develop its procedural significance. No other standard historical legal dictionaries in the Law Mind corpus — not Bouvier, not Black's early editions — appear to carry this term, which itself signals how marginal it became even in historical legal reference work.
The reliance on Kelham places acoigne firmly in the tradition of Law French scholarship rather than common law doctrine. Researchers should treat Burrill's entry as a pointer to primary linguistic sources rather than as a substantive legal definition. The concept it describes — disqualifying partiality or association — has a rich doctrinal history under other terms, but acoigne itself did not survive as an operative legal word.
