Definition
A Law French term meaning "spurs." In legal contexts, esperons appears in the records of feudal tenure, where the rendering of a pair of spurs — typically gold spurs — constituted the service obligation by which a tenant held land from a lord. Such tenure by spur-service was one of the many nominal or honorary forms of serjeanty, the class of feudal land tenure defined by a specific personal service owed to the crown or a lord.
Why It Matters in Research
Researchers encountering esperons in primary sources are almost certainly working with Year Book material or early plea roll transcripts from the late thirteenth or early fourteenth century. The term is not a legal concept in its own right but a piece of the descriptive vocabulary used to define the conditions of feudal tenure. Its presence signals that the document in question is characterizing a serjeanty or quasi-serjeanty arrangement, and researchers should orient their analysis around the law of tenure, grand and petty serjeanty, and the incidents attached to those holdings.
The practical trap: because esperons is purely terminological rather than doctrinal, it will not appear in indexes organized around legal principles. It surfaces instead in verbatim Year Book extracts and in the formulaic recitations of inquisitions post mortem. Burrill's citation to Yearb. T. 1 Edw. II. 17 is the key anchoring reference — researchers working in that period should consult the Year Books of Edward II directly for context. Kelham's Norman-French dictionary, cited by Burrill in the variant spelling esporouns, is a useful secondary reference for anyone navigating Law French vocabulary in this era.
No significant evolution in meaning exists because the term did not survive as an operative legal concept beyond the feudal period. By the time systematic English legal lexicography began, esperons was already an antiquarian entry — a word preserved in dictionaries because it appeared in old records, not because it continued to carry legal weight.
Historical Dictionary Support
All three source dictionaries agree: esperons means spurs. Black's (1st and 2nd editions) give only the bare gloss. Burrill provides the substantive value, offering the period phrase "per les servic' dune piere des esperons orretz" — by the services of one pair of gold spurs — drawn from Year Book Trinity term 1 Edward II. This contextualizes what would otherwise be a one-word entry: the rendering of spurs was a real, if ceremonial, legal obligation capable of defining a tenure relationship. Burrill also records the variant spelling esporouns with a cross-reference to Kelham, which is useful since Law French spelling was highly inconsistent in manuscript sources and early printed Year Books.
None of the historical dictionaries elaborate on the legal consequences of spur-tenure or its place within the taxonomy of serjeanty. Researchers wanting doctrinal context must look beyond these entries to treatises on feudal tenure.
