Definition
To touch, reach, or border upon. A parcel of land is said to abut another parcel, a road, or a physical feature when its boundary meets or terminates at that thing. In older usage, the distinction was precise: the ends of a tract were said to abut, while the sides were said to adjoin. Modern usage has relaxed this distinction, and "abutting" now broadly describes property that is contiguous or immediately adjacent to a street, highway, or neighboring parcel — including cases where a narrow strip or right-of-way separates the two, provided they are practically contiguous.
The term appears most often in property descriptions, assessment statutes, highway law, and pleading, where precision about physical boundaries carries legal consequence.

Common Language
Modern common usage (Wiktionary): To lean against on one end; to end on, of a part of a building or wall.
Historical common usage (Webster's 1913): To project; to terminate or border; to be contiguous; to meet — with on, upon, or against; as, his land abuts on the road.
The common and legal meanings are closely related, but legal usage extends the concept beyond physical touching. Courts have held property to "abut" a street even when separated by a narrow intervening strip, provided the parcels are practically contiguous. The structural precision of old law — ends abut, sides adjoin — has no counterpart in ordinary speech and is easy to miss in historical legal sources.

Common Confusion
ABUT vs. ADJOIN: In classical property law, these were distinct. To abut was to touch end-to-end; to adjoin was to touch side-to-side. Burrill traces the distinction to feudal usage, and both Black's (1st ed.) and Bouvier preserve it. By the modern period, courts frequently use the terms interchangeably, and many statutes treat "abutting" and "adjoining" as synonymous. Researchers reading historical pleadings or conveyancing instruments should not assume the terms were used loosely; in context, the distinction may matter to the legal description being construed.
ABUT vs. ADJACENT: "Adjacent" is broader and does not require physical contact. "Abutting" implies contact or near-contact. Assessment statutes imposing special charges on "abutting" landowners are typically construed more narrowly than those using "adjacent" or "nearby."

Why It Matters in Research
Corpus researchers encounter ABUT most frequently in three contexts: property descriptions in deeds and conveyances, highway and street assessment law, and common-law pleading of trespass and boundary disputes.
In pleading, abuttals (the formal recitation of what a tract of land borders) were a required element in older real property actions. Errors in stating abuttals could be grounds for challenge. Rapalje & Lawrence cites the pleading treatises and the East and Saunders reporters for abuttal requirements; researchers tracing a historical boundary dispute should check those pleading rules before assuming a description was merely informal.
In assessment law, whether a property "abuts" a street determines liability for improvement charges. Courts split on whether a physically separated parcel can still be "abutting" for assessment purposes. This generates significant variation in state court decisions from the late nineteenth century onward, and corpus searches on assessment or special improvement districts should pair ABUT with FRONTAGE and ASSESSMENT.
The end/side distinction (abut vs. adjoin) is live in older deeds and survey descriptions. A researcher reading an eighteenth- or nineteenth-century metes-and-bounds description who encounters both terms in the same instrument should treat them as carrying their technical meanings unless context clearly indicates otherwise.

Historical Dictionary Support
The historical dictionaries agree on the core definition — to reach or touch — and all trace the classical end/side distinction back to a single citation, Cro. Jac. 184. This convergence suggests the distinction was well settled in English practice and was carried into American law as received doctrine rather than independently developed.
Bouvier adds two details the others omit or understate: first, the sense of "taking a new direction," meaning a bounding line changes course at the point of abutment (citing Spelman's Glossary); second, the modern softening toward "bound upon" (citing 2 Chitty on Pleading 660). This dual treatment — old law versus modern law — is the most complete of the historical entries and is worth consulting directly when the vintage of a source matters.
Burrill provides the most thorough treatment of the term's structural meaning, tracing it to feudal usage through Spelman and explaining the spatial logic: to thrust forth the end, to terminate, to bound end-ways. His entry is useful when a researcher needs to explain, in a historical context, why the distinction between abutting and adjoining was meaningful rather than arbitrary.
Anderson's entry ("to touch or meet") and the first edition of Black's are minimal and add nothing beyond the core. The second edition of Black's is the most practically useful: it acknowledges the modern broadening, notes that abutting property may be separated by a narrow strip and still qualify as abutting, and signals the case law that developed this expansion — a development the earlier dictionaries do not reflect.
What the historical dictionaries collectively miss is the assessment-law context, which generated the bulk of nineteenth- and early twentieth-century litigation over the term's meaning. Researchers should not expect historical dictionary entries to resolve questions about special improvement districts or frontage assessments; that doctrine grew up in the reporters, not the glossaries.

Jurisdictional Note
Whether physically separated property can be "abutting" for statutory purposes varies by state and by the specific statute being construed. Courts in Illinois and Kansas addressed the question in cases cited in Black's 2nd edition; other states reached different results. Researchers working with assessment, zoning, or right-of-way statutes should treat the word as jurisdiction-specific rather than relying on the general common-law definition.
