Definition
An abator is a person who wrongfully obtains possession of a freehold estate after the death of the prior owner but before the rightful heir or devisee has had the opportunity to enter and take possession. The abator acquires this possession without any legal right of entry, effectively jumping ahead of the person entitled to inherit, and thereby prejudicing that heir or devisee.
The term carries a secondary meaning in tort law: one who abates, removes, or destroys a nuisance. In this sense the word is largely descriptive and carries no wrongful connotation — an abator of a nuisance acts lawfully, even commendably.
These two meanings are distinct enough that context is essential to interpretation.

Common Language
Modern common usage (Wiktionary): "A person who, without right, enters into a freehold on the death of the last possessor, before the heir or devisee."
Historical common usage (Webster's 1913): "(a) One who abates a nuisance. (b) A person who, without right, enters into a freehold on the death of the last possessor, before the heir or devisee. Blackstone."
The common definitions here track the legal ones closely, which is unsurprising — this is a term that migrated from law into general dictionaries rather than the other way around. Researchers should note, however, that ordinary usage tends to flatten the wrongfulness inherent in the property-law sense, and completely misses the procedural consequence: the abator's entry does not merely inconvenience the heir; it creates a legal problem requiring specific remedial action.

Common Confusion
ABATOR is sometimes loosely conflated with DISSEISOR. The distinction matters. A disseisor ousts someone already in possession of a freehold. An abator enters during the gap between an ancestor's death and the heir's entry — the heir has not yet taken possession, so there is no one to oust. The wrong is different, the procedural remedy historically differed, and the historical sources treat them as separate categories. Conflating the two when reading older real property materials will produce errors.
The nuisance-law meaning (abator as one who removes a nuisance) is so different in character from the property-law meaning that context should resolve any ambiguity, but researchers reading across subject areas in historical sources should not assume one meaning when they encounter the other.

Why It Matters in Research
ABATOR belongs to a cluster of archaic real property concepts that appear frequently in early English and American property law materials but have largely disappeared from modern practice. Several research traps attach to the term.
First, the procedural remedy historically available against an abator — the writ of entry — is itself an obsolete form of action. Materials discussing abatement of freehold will often assume familiarity with the writ system; researchers working in modern property law may not recognize the procedural scaffolding the older sources take for granted.
Second, the term appears in two completely unrelated legal contexts (property and tort/nuisance), and historical dictionaries — including the sources for this entry — tend to list both meanings in sequence without always making the categorical separation explicit. Reading selectively can produce a mistaken impression of the term's meaning in a given passage.
Third, American adoption of English real property concepts was uneven. Colonial and early republic sources may use ABATOR in the English technical sense; later American materials may use it more loosely or abandon it entirely in favor of statutory language addressing wrongful possession.
Fourth, researchers encountering ABATOR in older indices or digests should check whether the passage concerns freehold entry (a property matter) or nuisance (a tort matter) before pulling adjacent materials — the case law is organized under different doctrinal heads.

Historical Dictionary Support
The four historical sources consulted are in substantial agreement on both meanings. Black's (1st and 2nd editions) and Bouvier's each present the freehold-entry definition as primary and the nuisance definition as secondary. Burrill leads with the nuisance sense ("one who removes a nuisance") before turning to the property sense, which is a minor organizational divergence without substantive consequence.
All sources cite Littleton's Tenures as foundational authority for the property-law definition — Bouvier cites § 397, Burrill cites § 475, a discrepancy likely attributable to different editions or numbering conventions. Bouvier adds Preston on Abstracts and references to Washburn on Real Property, providing the most developed bibliographic trail for further research.
None of the historical sources engage meaningfully with the procedural mechanics of how an heir displaced an abator, nor do they address how American courts adapted or abandoned the concept after abolition of the forms of action. The nuisance meaning is treated as self-evident in all four sources — none explains what conduct qualifies as "abating" a nuisance or what legal authority is required. Researchers should not treat these entries as sufficient for substantive analysis; they establish the vocabulary, not the doctrine.

Jurisdictional Note
The property-law meaning of ABATOR is rooted in English common law and is most relevant in jurisdictions that received English real property law directly. In the United States, abolition of common-law forms of action and the modernization of property statutes have rendered the term largely historical. It retains analytical relevance when interpreting older deeds, title chains, or early American court opinions, but modern practitioners in most U.S. jurisdictions will not encounter it as an operative legal category.
