Definition
In old English law, a ring; specifically, the ring or handle of a door. The term appears in medieval legal texts as a physical marker for the formal act of delivering seisin or surrendering possession of a dwelling. Delivery of possession could be symbolized by the physical gesture of handing over, or touching, the hasp or ring of the outer door — per haspam vel annulum hostii exterioris — as a stand-in for transfer of the property itself.
The term has no independent operative meaning in modern Anglo-American law. It survives only as a Latin technical word embedded in early real property sources and the doctrinal literature on livery of seisin.

Common Language
Modern common usage (Wiktionary): A ring- or donut-shaped area, object, or structure; in anatomy and cardiology, a fibrous ring around a heart valve opening; in astronomy, a ring of light associated with an annular eclipse.
Historical common usage (Webster's 1913): A ring; a ringlike part or space; specifically, the geometric figure formed between two concentric circles, or the solid of revolution produced by rotating a circle around an external axis in its plane.
The legal meaning is narrower and more specific than either modern or historical common usage. In law, annulus does not denote any ring-shaped form in the abstract but refers concretely to the door-ring of a dwelling as a ceremonial object in the conveyance of real property. A researcher encountering the word in a scientific, anatomical, or astronomical context will find no bridge to its legal usage.

Why It Matters in Research
Annulus is essentially a fossil term — preserved in legal dictionaries because it appears in Fleta, one of the foundational treatises of early English law, but carrying no living doctrinal weight. Researchers will encounter it almost exclusively in two contexts: (1) reading or translating medieval Latin legal texts, particularly those dealing with conveyancing, seisin, and the formal transfer of land or tenements; and (2) tracing the history of livery of seisin as a doctrine.
The critical navigational point is that annulus functions here not as an abstract legal concept but as a physical prop in a legal ceremony. Medieval English law required an observable, public act to transfer possession of land — words alone were insufficient. The door-ring stood in for the property itself, making the touch or delivery of the annulus ostii a legally cognizable act of transfer. Understanding this ceremonial context is essential to reading the Fleta passage correctly.
Researchers working in the Law Mind corpus should connect this term directly to livery of seisin and the broader cluster of formal conveyancing acts (feoffment, investiture, attornment). The term will not appear in post-medieval English or American sources in any operative legal sense. If it appears at all in later texts, it is almost certainly either a direct quotation from Fleta or a commentator glossing that passage.
One trap worth flagging: the near-homophony and visual similarity between annulus (ring) and annus (year) can cause confusion in manuscript and early print sources where abbreviation and scribal conventions blur the distinction. This is a paleographic hazard more than a doctrinal one, but it can produce misreadings in untranslated texts.

Historical Dictionary Support
All three sources — Black's (1st ed.), Black's (2nd ed.), and Burrill — are in complete agreement. Each defines annulus as "a ring; the ring of a door" and each cites the identical passage from Fleta (lib. 3, c. 15, § 5) as the sole authority. The minor variation in the Latin quotation across editions (huspam in Black's 1st, haspam in Burrill and Black's 2nd, haspam vel annulum hostii cxterioris in Black's 2nd — the last likely a typographical artifact) does not affect meaning.
The uniformity of these entries reflects the term's narrow scope: there is simply nothing more to say about it as a legal term than what Fleta says. None of the historical dictionaries attempt to connect annulus to broader doctrine or to explain the conveyancing ceremony it participates in. Researchers wanting that context must look to treatises on livery of seisin rather than to dictionary definitions of this word alone.
What the historical dictionaries collectively omit is any explanation of why the door-ring mattered — that is, the underlying theory of symbolic delivery that gave physical objects like the annulus their legal operative force. That gap is the main reason a researcher encountering this term in a primary source needs to pursue the livery of seisin literature directly.
