Definition
A unit of land measurement used in medieval English law denoting a fourth part of a yardland (also called a virgate). The ferlingata represented one quarter of whatever acreage constituted the local yardland, a figure that itself varied by manor and region. It was a customary rather than a fixed measure, used primarily in conveyancing, taxation, and feudal tenure records.
Common Confusion
FERLINGATA and FERLINGUS (or FERLINGUM) are distinct terms that appear in proximity in the historical sources and are easily conflated. Ferlingata is a measure of land area — a quarter of a yardland. Ferlingus or ferlingum denotes a furlong, a measure of linear distance. Though both derive from the same root concept of a "fourth part," they operate in different domains of measurement. A researcher encountering either term in a medieval or early modern document should determine whether area or distance is at issue before proceeding.
Why It Matters in Research
Researchers working with early English land records, inquisitions post mortem, manorial surveys, or feudal tenure instruments will encounter ferlingata as a unit embedded in local custom rather than national statute. Because the yardland itself had no fixed acreage — commonly ranging from 15 to 40 acres depending on the manor — ferlingata is equally variable. A quarter-share of an undefined whole requires the researcher to anchor the measurement in the specific manor's customs or survey documents.
The term appears almost exclusively in pre-modern sources, and its practical significance is largely confined to records predating the systematic land surveys of the 18th and 19th centuries. Researchers should be cautious about treating ferlingata as interchangeable with fardel or fardingdeal, which the historical dictionaries cross-reference but which carry their own terminological histories. Burrill's cross-reference to both fardel and fardingdeal is a useful navigational signal: those entries may supply additional context missing from the ferlingata entry itself.
For corpus researchers, ferlingata is a marker term — its presence in a document strongly suggests pre-modern English agrarian law, manorial administration, or feudal land tenure. If it appears in a legal instrument alongside related terms such as virgate, bovate, or hide, the document is almost certainly concerned with the allocation, transfer, or taxation of customary landholdings under the open-field system or its successor frameworks.
Historical Dictionary Support
All four source dictionaries agree on the core definition: a fourth part of a yardland. The entries are brief and consistent, reflecting the term's narrow, technical function. Burrill adds the most navigational value, directing researchers toward fardel and fardingdeal as related concepts and citing Cowell's legal dictionary as authority — a citation that points to John Cowell's Interpreter (1607), a significant early glossary of English legal terms. Bouvier is notable for presenting ferlingata in direct sequence with ferlingus and ferlingum, making the proximity of the two distinct concepts visible and underscoring the confusion risk noted above. Black's (both editions) provides the definition without elaboration or cross-reference, reflecting the diminished practical relevance of the term by the time those editions were compiled.
None of the historical dictionaries address the variability of the yardland itself, which is the key limitation of the definition as stated. Researchers relying solely on the dictionary gloss — "a fourth part of a yardland" — without accounting for local variation may draw false equivalences across documents from different manors or regions.
Jurisdictional Note
Ferlingata is a term of English origin and is encountered almost exclusively in English legal and historical records. It has no recognized application in Scots, Irish, or American legal traditions. Welsh manorial records may employ analogous units under different names.
