Definition
An obsolete term from old English law denoting a fine or amercement — a monetary penalty imposed by a court or lord upon an offender. The term refers to the same underlying concept as the related forms gersuma, gressume, and grossome: a sum exacted as punishment or compulsory payment, typically in a feudal or manorial context.
Common Confusion
Garsumme is one of several variant spellings of the same underlying term. Burrill notes the correct form is properly gersuma, with garsumme, gressume, and grossome representing orthographic variants found across historical manuscripts and legal records. Researchers encountering any of these spellings in old English sources are likely looking at the same legal concept. The variation is a product of inconsistent medieval orthography, not meaningful legal distinction. Do not treat these as separate institutions without confirming context.
Why It Matters in Research
This term will appear almost exclusively in pre-modern English legal records — manorial rolls, court records, and early common law sources — and is essentially a dead letter in any modern legal system. Researchers should be aware of several practical traps:
Spelling variation is the primary research hazard. A search for garsumme alone will miss the same concept recorded as gersuma, gressume, or grossome in different documents or editions. Any corpus search must account for all four variants, and likely additional corruptions.
The term is definitionally thin in all source dictionaries, each deferring to Cowell's Interpreter (1607) as the authoritative reference. This means the historical dictionaries are themselves secondary sources on this point, and researchers seeking fuller treatment should consult Cowell directly or turn to Blount's Nomo-Lexicon, which Burrill cites for the variant spellings.
The relationship to amercement is the conceptually important connection. Amercement was the general mechanism by which monetary penalties were imposed in early English courts — distinct from a fixed statutory fine — and garsumme appears to have been used as a synonym or near-synonym in that tradition. Understanding amercement illuminates the legal function of garsumme far better than the bare definitions in the historical dictionaries do.
No meaningful modern research application exists for this term in its own right. Its value is as a paleographic and lexicographic key to unlock references in historical documents, not as a legal concept with ongoing doctrinal significance.
Historical Dictionary Support
All four source dictionaries converge on the same minimal definition — a fine or amercement — and all trace the term to Cowell. There is no substantive divergence among them. Burrill is the most informative of the four, adding that the proper form is gersuma and citing Blount's Nomo-Lexicon for the variant spellings. Bouvier cross-references gressume, grossome, and gersuma, directing researchers to those entries rather than expanding the definition here. Black's both editions add nothing beyond the Cowell attribution.
What the historical dictionaries do not do is explain the feudal context in which such fines arose, the distinction (if any) between garsumme and other forms of monetary exaction in manorial or ecclesiastical courts, or the procedural mechanisms by which such sums were assessed. Researchers needing that context must look beyond the dictionary shelf entirely — to manorial law sources, Maitland's work on early English legal history, or Pollock and Maitland's History of English Law.
