Definition
Elisio is a Latin term meaning the defeating or destroying of something — derived from the verb elidere, meaning to strike out, suppress, or annul. In legal usage, the term appears primarily in connection with pleading and procedural doctrine, where it denotes the nullification or destruction of a legal position, claim, or instrument by operation of some countervailing legal force.
The term is closely bound to the related noun elisors (also spelled eslisors), which designates the persons appointed to perform jury selection when both the sheriff and the coroner are disqualified from acting. Though etymologically distinct — elisors derives from the French eslier, to choose, rather than from elidere — the two terms appear together in historical legal writing and are often treated in tandem.
Common Confusion
Elisio and elisors are frequently run together in older sources, including Burrill, which introduces elisors immediately after defining elisio. The two terms are unrelated in meaning. Elisio refers to destruction or defeat of a legal interest. Elisors refers to court-appointed jury selectors. A researcher encountering either term in a historical source should confirm which is actually at issue before drawing conclusions about the subject matter of the document.
Why It Matters in Research
Elisio appears rarely as a standalone headword in legal sources and is most often encountered in passing, in the context of pleading treatises or Latin maxims addressing the effect of one legal act upon another. Its primary research value is as a key to interpreting Latin passages in older common law materials where the concept of legal nullification or suppression is at issue.
The proximity of elisio to elisors in historical dictionaries — including Burrill — creates a consistent indexing hazard. Sources that alphabetize loosely or that use running headwords may group these terms together in ways that obscure their independence. Researchers working in older digest systems or manuscript indices should treat any entry beginning with "elis-" with care and read the full context before assuming subject matter.
Elisio also appears in the broader family of Latin legal terms concerned with the mechanics of pleading — terms like elision, abatement, and estoppel all describe ways in which a legal position may be disabled or destroyed. Understanding elisio assists in reading pleading-era materials where these concepts interlock.
Historical Dictionary Support
Burrill's Law Dictionary is the principal historical source providing a formal definition of elisio. Burrill defines it tersely — "defeating or destroying" — and immediately transitions to the entry for elisors, reflecting the alphabetical proximity of the two terms rather than any conceptual relationship. The brevity of the elisio entry in Burrill suggests the term was not in active standalone use by the mid-nineteenth century but was recorded for completeness as a Latin root appearing in older authorities.
No extended treatment of elisio appears in the other major historical law dictionaries, and the term does not feature prominently in Blackstone or the leading pleading treatises as a freestanding concept. Its preservation in legal dictionaries is largely attributable to its function as a definitional bridge — explaining the Latin roots that appear in older case law and ecclesiastical sources — rather than to its independent doctrinal significance.
Researchers should note that historical sources do not treat elisio as a term of art with a formal legal test or defined set of elements. It functions descriptively rather than as a technical category of doctrine.
Jurisdictional Note
Elisio has no jurisdiction-specific meaning in modern American or English law. It is a Latin term of historical and interpretive relevance only, without distinct treatment in any particular common law jurisdiction.
