Definition
To detect or discover a secret crime and disclose it to a magistrate or other authority. The term appears in medieval English legal texts and describes the act of exposing concealed wrongdoing — not merely witnessing or suspecting it, but bringing it to the attention of a person in official capacity. The past participle form, abarnatus, means discovered or detected, and describes the state of a crime or person so exposed.
The term is purely archival. It has no operative role in modern law and appears only in historical sources rooted in Anglo-Saxon and early Norman legal codes.
Common Confusion
Abarnare should not be confused with mere accusation or denunciation. The term carries a specific connotation of discovery — uncovering something hidden — rather than simply reporting a known offense. The disclosure element is inseparable from the detection element; a person who witnesses an open crime and reports it is not abarnare in the technical sense. The word implies that the crime was secret and that the act of disclosure itself constituted its revelation.
Why It Matters in Research
This term belongs to the stratum of Law Mind sources dealing with pre-Conquest and immediately post-Conquest English law. Researchers will encounter it only in one context: glossaries and commentaries on the Leges Canuti (Laws of Cnut) and the Leges Henrici Primi. These are compilations of early medieval English law, written in Latin, and the term reflects the hybrid Anglo-Saxon/Latin legal vocabulary of that period.
Two practical research notes apply here:
First, variant orthography is a live problem. Medieval legal Latin manuscripts and their printed transcriptions were not standardized. A researcher scanning historical indexes or early printed law dictionaries for this term may find it under abarnar, abarnatus, or not indexed at all. Burrill's entry provides the Saxon root (abarian) as a navigational clue when tracing the term into non-Latin sources.
Second, the chapter references in the source dictionaries do not fully agree. Black's cites Leges Canuti, cap. 10; Burrill cites both LL. Hen. I. c. 91 and LL. Canuti, c. 104. This discrepancy is common in citations to early medieval codes, which circulated in multiple manuscript versions with inconsistent chapter numbering. Do not treat either citation as definitive without consulting the underlying text directly.
For researchers working on the history of criminal procedure, informer liability, or the duty to report crime, abarnare is a useful conceptual ancestor — evidence that early English law recognized a formal category for the act of bringing hidden crimes to light, distinct from witness testimony about observed acts.
Historical Dictionary Support
The three source dictionaries are in agreement on the core definition: detection of a secret crime followed by disclosure to authority. Burrill adds the most useful information, providing the Saxon etymological root and the adjectival form abarnatus, which extends the term's utility for reading primary sources where the verb form may not appear.
Black's (both editions) is more compressed and routes directly to the Leges Canuti without the additional Leges Henrici Primi reference that Burrill supplies. Neither edition of Black's flags the chapter numbering discrepancy noted above — a gap researchers should carry into any primary source work.
None of the three dictionaries situate the term within a broader discussion of early English criminal procedure or compare it to related duties of disclosure in contemporaneous legal systems. The entries are definitional only. Cowell's Interpreter, cited by Burrill as a secondary source, provides the most accessible early modern discussion and may be the better starting point for contextual research than the dictionaries themselves.
Jurisdictional Note
Abarnare is specific to early English law. It has no recognized equivalent in Scottish, Irish, or continental civil law traditions, and no American legal usage exists.
