Definition
Ocrimen is a Latin term used in historical legal texts to mean "crime" or, more specifically, an accusation or charge of crime. It appears primarily in medieval and early modern legal writings, where Latin remained the language of formal legal discourse. The term encompasses both the underlying criminal act and the formal accusation brought against a person. In practice, ocrimen functioned as a prefix or root in a family of compound Latin legal phrases, each designating a specific category of offense.
Recognized compound forms include:
1. Crimen furti — the crime of theft.
2. Crimen incendii — the crime of burning. Historically broader than modern arson, this category included the burning of a person, an animal, or other chattel, not merely the burning of a dwelling or structure.
3. Crimen innominatum — literally "the nameless crime." Used to denote the crime against nature, encompassing sodomy and buggery. The designation as "nameless" reflected the reluctance of medieval legal writers to name the act directly in formal text.
4. Crimen raptus — the crime of rape or violent abduction.

Common Confusion
Ocrimen should not be confused with the modern English word "crime" in any technical sense. The term functions in Law Mind's corpus as a Latin headword giving access to a cluster of compound phrases rather than as an independently operative legal term. Researchers unfamiliar with this structure may miss the compound entries when searching only for the English equivalents.
Additionally, crimen incendii should not be conflated with the modern offense of arson. The historical category was substantially broader, and applying a modern arson definition to sources using crimen incendii will produce anachronistic results.

Why It Matters in Research
Researchers working in medieval, early modern, or ecclesiastical legal sources will encounter ocrimen and its compounds with some frequency. Several research traps are worth noting.
First, the term signals Latin-language source material. Documents and treatises using ocrimen are typically drawn from a pre-vernacularization legal tradition, and the same concept may appear under entirely different terminology in contemporaneous English-language sources. Researchers must be prepared to work across both vocabularies.
Second, the scope of the underlying offenses often differs from modern equivalents. Crimen incendii is the clearest example: sources using this phrase encompass conduct that modern law would classify separately as arson, assault, animal cruelty, and property destruction. Mapping historical crimen categories onto modern offense categories requires care.
Third, crimen innominatum is a term with significant historical and rhetorical weight. Its appearance in a source is itself informative — the "nameless" designation was a deliberate rhetorical strategy, and the phrase was used with enough consistency across canonical and common law sources to constitute a recognized legal category, not merely a euphemism.
Fourth, the dual meaning of ocrimen — both the act and the accusation — mirrors a broader ambiguity in early criminal law between the offense itself and the procedural charge. Researchers analyzing early accusatorial versus inquisitorial procedure will find this ambiguity relevant.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) treats ocrimen as a Latin headword and uses it as an organizational anchor for the cluster of crimen compounds. This is consistent with the dictionary's broader practice of collecting Latin legal vocabulary that would otherwise be inaccessible to readers working only with English-language indices.
Black's entry for crimen incendii cross-references Britton (Britt. c. 9) and Crabb's English Law, indicating that the term's expanded scope beyond modern arson was recognized and documented in the primary treatise tradition. The reference to Britton is particularly significant: Britton is a late thirteenth-century English legal treatise written in Law French rather than Latin, which illustrates how these Latin crime categories moved across linguistic registers in medieval legal literature.
Black's entry is notably incomplete as reproduced — the crimen raptus entry is truncated. Researchers relying solely on this edition should be aware that the definition of crimen raptus, which encompassed both forcible rape and abduction (and the overlap between them in historical law), is not fully captured in the available text.
No other historical dictionary sources are available in the Law Mind corpus for this term. The absence of entries in sources such as Bouvier's Law Dictionary or Tomlin's Law Dictionary does not indicate that the term was unrecognized, but rather reflects the varying coverage of Latin legal vocabulary across historical dictionaries.

Jurisdictional Note
Ocrimen and its compound forms appear across English common law, canon law, and continental legal traditions. The specific scope of each crimen category could vary by jurisdiction and era. Crimen raptus, in particular, carried different boundaries in canon law and secular common law, and researchers should not assume uniform meaning across traditions.
