Definition
Merannum (also rendered *merannum*) is a term appearing in old English legal records denoting timber or wood designated for building purposes. It refers specifically to structural lumber — the raw material of construction — rather than wood generally or wood used for fuel. The term surfaces in medieval property documents, surveys, and conveyances where rights to timber, or the presence of building materials on a parcel, required formal notation.

Why It Matters in Research
This is a term of exclusively archaic documentary provenance. Researchers will encounter merannum only in medieval or early modern English records — manor court rolls, surveys, conveyances, and similar instruments predating the standardization of English legal vocabulary. Its practical significance in those records is straightforward: it signals that building timber was present on or attached to the property being described, which could bear on rights of waste, terms of tenure, or the assessed value of an estate.
The chief trap for researchers is misreading or misidentifying the term in manuscript sources, where spelling variants and abbreviated forms were common. Neither Black's edition records variant spellings, so researchers working from primary documents should expect orthographic flexibility. If the term appears in a record alongside other timber-related terminology — such as *estovers* (the right to take wood) or *boscus* (woodland generally) — understanding merannum as a specific category of building timber, distinct from firewood or fence-wood, is essential to parsing the legal significance of the passage.
There is no modern statutory or common law context in which this term is operative. Its relevance is confined to historical legal research, particularly in English land records and property history before roughly the seventeenth century. Researchers working on American colonial records may encounter it in documents with English antecedents, but it does not appear to have carried forward into American legal usage.

Historical Dictionary Support
Both Black's Law Dictionary and its Second Edition record merannum in substantially identical terms: "timbers; wood for building," noted as appearing "in old records." The two editions offer no elaboration beyond this minimal identification, and neither provides documentary examples, variant spellings, or citations to specific instruments where the term was construed. This is consistent with Black's treatment of obsolete Latin and law-French terms that had passed entirely out of active use by the time those editions were compiled.
The absence of any judicial construction or treatise discussion in the historical sources reflects the term's status as a descriptive word of record rather than a term of legal art with contested meaning. No significant divergence exists between the two editions — the Second Edition simply inverts the word order of the entry. Researchers should not expect to find merannum discussed in Coke, Blackstone, or other canonical common law authorities; its habitat is the documentary record of land administration, not the jurisprudential literature.
