Definition
Mor is an archaic Latin term appearing in historical legal texts, most commonly as an abbreviation or contraction. In the context of Anglo-American common law sources, it appears principally in two related usages:
1. As a shortened form of "mors" (Latin: death), used in older pleading and conveyancing to signal a matter touching on the death of a party, particularly in real actions and writs where the life or death of an ancestor was legally operative.
2. As a variant abbreviation appearing in marginalia and editorial notes of early American and English law reporters, where it sometimes signals "moreover" or serves as a cross-reference marker in compiled digests.
The term has no independent legal force as a standalone doctrine or rule. Its significance is purely referential and contextual — it is a textual artifact of Latin-inflected legal writing rather than a term of art carrying its own substantive legal meaning.
Common Language
Modern common usage (Wiktionary): A mid-ocean ridge; a submarine volcanic mountain range.
Historical common usage (Webster's 1913): Not listed as a standalone entry; "mor" does not appear as an independent English word in Webster's 1913.
The gap here is total rather than merely meaningful: the modern common English usage (geological formation) has no connection whatsoever to the legal usage. A researcher encountering "mor" in a 19th-century legal reporter or digest should not import any sense of the modern term. The legal appearance is either a Latin abbreviation or an editorial shorthand, not an English word.
Common Confusion
Mor is easily confused with "more" (a comparative adjective appearing in statutory and contractual interpretation questions) and with "mora" (the distinct Latin legal term meaning delay or default in performance, which carries substantive doctrinal weight in civil and contract law). These are different terms. Mora generates its own legal consequences — particularly in civil law systems regarding interest accrual and damages — while mor does not. Researchers working in early American or colonial materials who encounter "mor." with a terminal period should treat it as an abbreviation and consult the surrounding context to determine whether it signals mors (death), moreover (transitional), or some other referent specific to the source.
Why It Matters in Research
The practical research significance of "mor" is almost entirely navigational. When it appears in Burrill's Law Dictionary and the surrounding material — as the source excerpt confirms — it sits adjacent to discussion of the term "month" and its statutory redefinition in New York, as well as references to English common law rules followed or reversed in Georgia, Alabama, and Virginia (Grattan's Reports). This strongly suggests that "mor" in the Burrill source is functioning as an abbreviation or truncation artifact of the compilation process rather than as a defined term in its own right.
Researchers using Burrill should be aware that the dictionary was composed using extensive abbreviation and cross-referencing conventions typical of mid-19th century American legal digests. Apparent "entries" may in fact be mid-paragraph continuations, footnote residue, or cross-reference signals. The page range in the source excerpt (pages 209–211, running through material on Lombards and the laws of Canute) places the fragment in a discussion of monetary or temporal legal concepts inherited from medieval English and continental sources.
If you encounter "mor" in a colonial-era or early republic document, check first whether it is "mora" (civil law delay), "mors" (death, operative in real actions), or simply an editorial note. Burrill itself is a useful starting point for 19th-century American common law vocabulary but predates the full statutory reform era and must be read against later state-specific codifications.
Historical Dictionary Support
Burrill's Law Dictionary does not define "mor" as a standalone term with independent legal content. The appearance of the fragment in the source material is contextual — it falls within a larger discussion touching on the legal definition of "month," divergence between English common law and American state practice, and historical antecedents in Lombard law and the laws of Canute. Burrill frequently incorporates Latin abbreviations without separate definitional treatment, expecting readers fluent in the Latin legal vocabulary of the period.
No other historical legal dictionary in the standard shelf — Black's, Bouvier's, Tomlin's — treats "mor" as a defined term of art. This absence is itself informative: it confirms that the term functions as shorthand rather than doctrine.
Jurisdictional Note
No jurisdiction recognizes "mor" as a term of art in modern statutory or case law. Its relevance is confined to historical document interpretation, primarily pre-codification American and English common law sources.
