Definition
An obsolete English land measure, also rendered as *sulinga* in medieval Latin sources. A sulling denoted a unit of land corresponding roughly to what was elsewhere called a plough-land — that is, the amount of arable land that could be worked by a single plough team in a year. The term appears principally in records from Kent and southeastern England, reflecting a regional vocabulary for land assessment that diverged from the hide system used in other parts of the country. Some sources also associate the term with a reference to alders (elder trees), suggesting possible use as a boundary or topographical marker in certain contexts, though the primary meaning is the land-measure sense.

Common Language
Modern common usage (Wiktionary): Present participle and gerund of "sull" — a dialectal or regional English verb meaning to plough or till the soil.
Historical common usage (Webster's 1913): Not attested in Webster's 1913.
The common verb form ("sulling" as ploughing) is etymologically connected to the legal noun, both deriving from the same root concept of plough-work. Researchers should not confuse an incidental gerund form in a document with the technical land-measure term; context — particularly the presence of acreage calculations, tax assessments, or conveyance language — will distinguish the legal usage from descriptive agricultural narrative.

Why It Matters in Research
Sulling is a hyper-regional term, concentrated in Kentish records from the Domesday period and the centuries immediately following. Researchers working with medieval land grants, inquisitions post mortem, or early taxation rolls from Kent need to recognize it as functionally equivalent to the hide or carucate used in other regions — but not identical in acreage, since the Kentish sulling could vary in size according to local custom and soil quality.
The trap in historical sources is the inconsistent spelling. Burrill records the Latin form as *sulinga*, and Cowell cross-references it under "Swoling" — a variant that differs enough in spelling that keyword searches in digitized corpora may miss matches entirely. Researchers should cast a wide net: sulung, sullung, sulinga, swoling, and swalung are all documented variants. Running any one of these spellings alone through a corpus search will return an incomplete picture.
The gloss in Coke on Littleton (Co. Litt. 4b), cited by Burrill, equating sullings with "elders" (alder trees) is a point of scholarly confusion that has never been fully resolved. It may reflect a scribal corruption, a localized secondary meaning, or a misreading in Cowell's original handling. Researchers citing this passage should treat it cautiously and not generalize from it to the land-measure definition.
Because sulling is a Kentish regionalism, it will rarely appear in sources dealing with land tenure in the Midlands or northern England. Its presence in a document is itself a locating signal — pointing toward southeastern English provenance — that can assist in dating or placing undated materials.

Historical Dictionary Support
Burrill is the primary authority among the standard legal dictionaries, and his entry is brief but accurate in its essentials: sulling equals plough-land, the Latin form is sulinga, and he prudently routes the reader to Cowell for further detail. The Coke citation (Co. Litt. 4b) is the oldest English legal authority Burrill invokes, and it remains the standard textual anchor for the term.
What the historical dictionaries do not provide is any systematic treatment of acreage equivalents or regional variation in the size of the sulling. For that, researchers must move beyond the legal dictionaries to Domesday scholarship and medieval agrarian history. The sulling's relationship to the Kentish lath system — the administrative unit above it — is also entirely absent from the dictionary literature and must be recovered from primary records and specialized secondary sources.
No material divergence exists among the historical legal dictionaries on the core definition; the disagreement, such as it is, concerns the alder-tree gloss in Cowell/Coke, which remains unexplained.

Jurisdictional Note
Sulling is effectively a single-jurisdiction term: Kent and the immediately adjacent areas of southeastern England. It has no meaningful currency in Scottish, Irish, Welsh, or other English regional legal traditions. Researchers working outside that geographic footprint are unlikely to encounter it except in comparative or definitional passages.
