Definition
In old English law, a wood or piece of wood-ground where ash trees grow. The term appears in medieval property and conveyancing records as a descriptor of land characterized by ash woodland, functioning as a classification of land type for purposes of tenure, grants, and boundary description.
Why It Matters in Research
FRASSETUM is a classificatory land term. Researchers encountering it in medieval deeds, charter grants, or conveyancing instruments should treat it as a descriptor of land character — ash woodland — rather than a term of legal right or tenure. Its significance lies in the physical description it provides, which could affect the scope of a grant, the rights associated with the land (such as estovers or timber rights), or the identification of boundaries in historical title chains.
Researchers working with Coke on Littleton (Co. Litt. 4b) will find this term in the context of land classification alongside terms like boscus (wood), moor, and heath — a family of descriptors defining the physical character of conveyed ground. Understanding these classifications together is essential; FRASSETUM does not stand alone in the tradition but belongs to a cluster of terms differentiating woodland types by dominant species or use.
One textual caution: the 2nd edition of Black's Law Dictionary cites Co. Litt. 40, while the 1st edition and other historical dictionaries cite Co. Litt. 4b. Researchers should verify the edition and pagination of their Coke on Littleton copy. The two citations likely reflect the same passage rendered differently across print editions of Coke — a common hazard in early legal literature.
Historical Dictionary Support
All five source dictionaries agree on the core definition: ash-wood ground. The entries are brief and consistent, indicating that FRASSETUM was not a contested or litigated term but simply a technical descriptor recorded for completeness.
Burrill's Law Dictionary adds the most substantive detail, noting that Blount — the 17th-century antiquary and legal lexicographer — considered FRASSETUM a corruption of the Latin FRAXINETUM, meaning a place where ash trees grow (from fraxinus, ash tree). Burrill also adds Sheppard's Touchstone (Shep. Touch. 95) as a secondary authority alongside Coke on Littleton. Researchers consulting property conveyancing materials from the early modern period may find FRAXINETUM used interchangeably with FRASSETUM; treating them as equivalent is appropriate given this etymology.
None of the historical dictionaries provide case law or legislative authority, consistent with the term's nature as a descriptive land classification rather than a legal doctrine. The omission is not a gap — it reflects the term's actual role in the sources.
