Definition
A Law French term meaning the end of blood, or the failure of the direct line of descent in a succession. In feudal and early common law property contexts, saunkefin described the condition arising when a decedent left no lineal heirs — no direct descendants capable of inheriting — causing the line of succession to terminate. The term was used to identify the specific circumstance of lineal extinction, distinct from a general failure of heirs, and carried consequences for how property would pass, escheat, or be distributed to collateral kin or the lord.

Why It Matters in Research
This is a rare, archaic Law French term encountered almost exclusively in medieval and early modern English legal sources, primarily the Britton and Year Books. Researchers are unlikely to encounter saunkefin in any post-17th-century legal instrument, treatise, or reported case. Its value is interpretive: when reading early property records, feudal tenure documents, or legal antiquarian commentary, the term signals that the author is addressing the extinction of the direct bloodline specifically, not merely the absence of heirs generally.
The critical research distinction is between saunkefin (failure of the direct, lineal line only) and the broader concept of general failure of heirs, which would trigger escheat to the lord. Rapalje & Lawrence's phrasing — "determination of the lineal race" — highlights that saunkefin concerns lineage exhaustion, not a simple lack of any surviving relative. This distinction mattered in feudal property law because collateral heirs might still inherit even after saunkefin, depending on the tenure and the rules of the relevant jurisdiction or custom.
Researchers working in ecclesiastical succession, feudal tenures, or early inheritance disputes should trace the term to its cited sources: Britton (chapter 119 in Rapalje & Lawrence, chapter 19 in Burrill) and Spelman's Glossarium Archaiologicum and Cowell's Interpreter — both foundational reference works for Law French vocabulary. Burrill usefully notes the neighboring term sauns (without), which appears in related Law French constructions; researchers should not conflate these.
Because all four dictionary sources offer nearly identical definitions tracing back to the same two or three primary authorities (Spelman, Cowell, and Britton), the term is well-settled in meaning and has not generated interpretive controversy. Its appearance in a source is a reliable signal of feudal property context.

Historical Dictionary Support
All four sources agree on the core definition: end of blood, failure of the direct line in successions. Black's (both editions) and Burrill reproduce virtually identical text, each attributing the definition to Spelman and Cowell. Rapalje & Lawrence varies slightly in phrasing — "determination of the lineal race; a descent of kindred" — and cites Britton chapter 119, which provides a more contextual framing: the term describes not just the fact of lineal failure but its consequence for the descent of property among kindred.
Burrill adds the most surrounding context, noting the related term sauns and several Law French constructions from the Year Books, which suggests the word appeared in a cluster of related vocabulary in medieval pleading and property discourse. None of the sources provide significant doctrinal elaboration beyond the definition, which is expected: by the time these dictionaries were compiled, saunkefin had long passed out of active legal use and survived only as a term of historical reference.
Historical sources do not address whether saunkefin produced automatic escheat or merely triggered a new order of succession — a gap researchers should be aware of when interpreting primary sources. The answer likely depended on the specific tenure, the applicable custom, and the period.

Jurisdictional Note
The term is specific to the feudal English legal system and its Law French vocabulary. It has no recognized counterpart in American, Scottish, or civilian legal traditions. Researchers working in Anglo-Norman or early English common law contexts will encounter it; those working in any modern jurisdiction will not.
