Definition
An archaic Law French verb meaning to essoin — that is, to excuse or exempt a person from appearing in court. To assoner a party was to formally present an essoin on that party's behalf, claiming a recognized legal excuse (such as illness, travel, or royal service) that justified absence from a required court appearance. The party for whom the essoin was presented was said to be assoneed or essoined.
The term belongs to a cluster of procedurally linked Law French expressions governing absence from court. Assoner is the operative verb; the noun form is essoin; the party benefiting is the assonee.
Common Confusion
ASSONER should be distinguished from closely associated terms appearing in the same Law French procedural vocabulary. ASSOUDRE (or assoudre) meant to absolve or acquit — a substantive outcome, not a procedural excuse. ASSOYL carried a similar meaning of forgiveness or pardon. ASSOUTH denoted the state of being quit or discharged. A researcher encountering these terms in medieval and early modern records must distinguish between the act of excusing an absence (assoner), the state of acquittal (assouth/assoyl), and the act of absolving (assoudre). The shared prefix and visual similarity create genuine risk of misreading in manuscript sources.
Why It Matters in Research
Assoner is an extinct procedural term found almost exclusively in medieval English court records, Year Books, and early abridgments. Researchers working in those materials need to recognize it as part of the essoin system — a formal mechanism of the common law courts that allowed parties to delay proceedings through recognized excuses. The essoin system was procedurally elaborate: different categories of essoin applied in different circumstances, and the rules governing how many essoins a party could claim, and in what sequence, varied by court and era.
The critical navigational point is that assoner is the verb, not a noun describing a person or an institution. It will appear in procedural narratives describing what an attorney or friend did on a party's behalf, not as a title or status designation. In Burrill, it appears immediately adjacent to assoudre, assouth, and assoyl — terms that sound similar but describe entirely different legal acts. Misreading one for another in transcription or citation can fundamentally alter the meaning of a passage.
The Fet Assaver reference in Burrill (§ 16) points to a genuine medieval source — a treatise on essoins forming part of the older common law literature — and is a useful anchor for researchers seeking the procedural context in which assoner operated.
Because this term is effectively obsolete and appears in only one of the Law Mind source dictionaries, researchers should treat it as a marker term: its presence in a document signals engagement with early common law pleading and procedure, likely pre-sixteenth century in origin or consciously archaizing.
Historical Dictionary Support
Burrill is the sole Law Mind source covering this term, and his entry is brief. He defines assoner as the Law French infinitive meaning to essoin, notes the past participle form assonee (or essoined), and cites Fet Assaver § 16 as authority. The entry is essentially a cross-reference to the broader essoin system rather than a self-contained definition.
Burrill clusters assoner with assoudre, assouth, and assoyl in sequence, suggesting he understood them as a family of related Law French terms requiring disambiguation — which is correct. The juxtaposition is editorially useful even if the individual entries are thin.
No other historical dictionary in the Law Mind corpus covers this term. Researchers needing fuller treatment of the essoin system should consult Burrill's entry for ESSOIN directly, where the procedural substance is developed at greater length.
Jurisdictional Note
The essoin system to which assoner belongs was a feature of the English common law courts. It did not transfer meaningfully to American practice, where the procedural apparatus of essoins was never adopted. The term has no modern American or comparative law usage.
