Why It Matters in Research
DRVU is a term of purely historical significance, appearing in Domesday Book and preserved in Black's as a record of medieval land description vocabulary. Researchers encountering it will do so almost exclusively in the context of Anglo-Norman land tenure documents or scholarship interpreting the Domesday survey. It has no operational legal meaning in modern common law and should not be read as a term of art carrying rights, duties, or legal consequences in any contemporary jurisdiction. Its value is cartographic and descriptive — it tells a reader something about the physical character of a parcel as recorded by Norman surveyors, not about the legal status of that land. Researchers working with Domesday-era records should be aware that many such descriptive terms were transcribed phonetically from Old English, Welsh, or Anglo-Norman originals and may appear in variant spellings across manuscript traditions.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the sole dictionary entry, defining DRVU tersely as "a thicket of wood in a valley" and citing Domesday as the source. No elaboration is offered, and the term does not appear to have attracted commentary in subsequent editions of Black's or in other historical legal dictionaries within the Law Mind corpus. The brevity of the entry reflects the term's narrow function: it was recorded because Domesday Book is a legal-historical document of foundational importance to English property law, and its terminology was catalogued accordingly — not because DRVU had any independent legal career. Researchers should treat the entry as a lexicographic artifact rather than a guide to operative law.
