Why It Matters in Research
Oncunne is a term a researcher is unlikely to encounter outside of historical legal documents, glossaries of Law French, or secondary scholarship on medieval English criminal procedure. Its practical significance is almost entirely paleographic and lexicographic: recognizing the word in a manuscript or early printed source and understanding that it maps to the modern concept of "accused" or "defendant in a criminal proceeding."
Researchers working in pre-modern English legal records — plea rolls, eyre rolls, or early Year Books — may encounter oncunne in contexts where the procedural status of a party is being described. Conflating it with terms denoting conviction or attainder would be an error; oncunne speaks only to accusation, not to a finding of guilt.
The term carries no surviving doctrinal weight in modern legal systems. Its appearance in Black's and Rapalje & Lawrence is essentially archival — preserving a word that had already become obsolete by the time those dictionaries were compiled, and tracing it to Du Cange's Glossarium Mediae et Infimae Latinitatis, the standard scholarly reference for medieval Latin and Law French terminology. Researchers who need to trace the word further should consult Du Cange directly.

Historical Dictionary Support
All three source dictionaries — Black's Law Dictionary (1st and 2nd editions) and Rapalje & Lawrence — agree precisely: oncunne means "accused" and attribute the term to Du Cange. There is no divergence among the sources on meaning, and none provides extended discussion. The entries are definitional stubs, consistent with treatment of obsolete Law French vocabulary that warranted preservation but no elaboration.
Rapalje & Lawrence place the entry in proximity to "One Day After Date" (a promissory note construction), which is alphabetical coincidence rather than conceptual connection and should not mislead researchers browsing the source.
Historical dictionaries do not address procedural context — whether oncunne appeared in specific writ forms, at particular stages of criminal proceedings, or in defined categories of courts. Researchers seeking that level of granularity must go beyond the dictionary record to primary sources and specialized scholarship on Anglo-Norman legal language.
