Definition
A Law French term meaning unreasonable. Desrenable appears in early English legal texts as the adjectival counterpart to reasonableness standards applied in medieval common law proceedings. Its sole recorded meaning across all historical sources is "unreasonable" — the negation of what a court or legal rule required to be reasonable in conduct, process, or judgment.

Why It Matters in Research
This term is a navigation marker, not a working legal concept. Researchers encounter desrenable almost exclusively when reading primary medieval sources — particularly Britton (c. 121), the late-thirteenth-century Anglo-Norman legal treatise attributed to John le Breton — and the historical dictionaries that gloss it. It does not appear as an operative term in modern legal doctrine.
The principal research trap is this: a researcher encountering desrenable in a manuscript or early printed source might not immediately recognize it as a simple negation of reasonableness. The Law French prefix des- functions as a privative (equivalent to the Latin dis- or in-), but the root renable (reasonable) is itself archaic enough that the compound may not be immediately transparent. Knowing the translation prevents misreading a procedural reasonableness requirement as something more arcane.
Corpus researchers should also note that Burrill's Law Dictionary reproduces desrenable in close proximity to two entirely distinct terms — destreindre (to distrain) and destrer (a war-horse) — because they fall together alphabetically. These terms share no legal relationship. Researchers scanning Burrill for any of the three should take care not to conflate neighboring entries that happen to share a similar Law French stem.
The sole authoritative citation across all source dictionaries is Britton, chapter 121. Any broader appearance of this term in medieval legal records would likely trace to the same reasonableness vocabulary found throughout that work.

Historical Dictionary Support
All five source dictionaries agree completely: desrenable means unreasonable. There is no divergence, no evolution, and no secondary meaning recorded in any of them. Black's (both editions), Bouvier's, Rapalje & Lawrence, and Burrill all anchor the definition to Britton, chapter 121.
The brevity of each entry reflects the term's status as pure lexical gloss — it existed to be translated, not to do independent legal work. Bouvier and Black's (1st ed.) give nearly identical one-line definitions. Rapalje & Lawrence offer only the translation with no citation. Burrill adds the citation and nothing more before moving to the next entry. Black's 2nd edition provides the least legible version of the entry due to apparent typesetting issues in the source text, but carries the same substance.
None of the historical dictionaries trace how or whether medieval courts applied the reasonableness standard that desrenable negated — that substantive analysis would require consulting Britton directly and the scholarship surrounding it.
