Definition
Ofera appears to be a transcription error or typographical corruption of the entry for OPERA as it appears in Black's Law Dictionary (2nd Edition, Supplemental volume). The intended term is opera: a dramatic composition set to music and performed by singers, accompanied by musical instruments, and presented with appropriate costumes and scenery. The venue in which operas are performed is termed an opera-house.
The entry's legal significance in Black's derives not from opera as a legal doctrine but from its relevance to property, licensing, entertainment contracts, and public amusement law — contexts in which courts were called upon to define or classify theatrical and musical performances for regulatory or liability purposes.
Common Confusion
Ofera should not be treated as an independent legal term. It is a corrupted rendering of opera and carries no separate legal meaning. Researchers should not attempt to locate doctrinal development for "ofera" as a distinct concept.
Why It Matters in Research
Researchers encountering "Ofera" in a Law Mind corpus search should treat it as a scanning or OCR artifact for the term OPERA. The original Black's 2nd Edition Supplemental entry for opera is a descriptive definition rather than a doctrinal one, and its appearance in a law dictionary reflects the 19th-century practice of including definitions for terms that arose in litigation — in this case, disputes over entertainment venues, amusement licensing, lease classifications, and related matters.
The single case citation in the Black's entry — Rowland v. Kleber, 1 Pittsb. R. (Pa.) 71 — is a Pennsylvania Pittsburgh Reports decision and represents the kind of local court authority that supported these definitional entries. Researchers working on historical entertainment law, theater licensing, or amusement venue regulation in Pennsylvania should note this citation as a potential primary source.
OCR and transcription errors of this kind are common in digitized versions of the Black's supplemental volumes. When a Law Mind search surfaces "Ofera," "Onera," or similar corruptions, cross-checking against the surrounding entry text and the cited case will usually resolve the intended term.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.), Supplemental, defines the term (intended as opera) as: "A composition of a dramatic kind, set to music and sung, accompanied with musical instruments, and enriched with appropriate costumes, scenery, etc." This is a functional, descriptive definition consistent with general usage of the period rather than a term of art with a technical legal meaning distinct from ordinary usage.
No divergence appears between the legal definition offered and the common understanding of the word. The dictionary's purpose in including the term was classificatory — to assist courts and practitioners in determining whether a given performance or venue fell within the meaning of "opera" for purposes of licensing, taxation, lease terms, or nuisance analysis. Historical legal dictionaries of this era routinely included such definitions to provide courts with authoritative reference points for terms appearing in contracts and statutes that were not themselves legal terms of art.
