Definition
A Law French phrase meaning "I give." In medieval legal usage, *jeo done* (also rendered *jeo doyne*) appeared as the operative word of gift in early conveyancing formulas. The phrase was not used in isolation but as part of structured bilateral expressions describing the consideration or cause underlying a grant or transaction. Britton, the thirteenth-century legal treatise, sets out four canonical formulas built on the phrase:
1. *Jeo done par si que tu me doynes* — I give for this that you may give me. (Do ut des: gift in exchange for gift.)
2. *Jeo face, par si que tu faces* — I do for this that you may do. (Facio ut facias: act in exchange for act.)
3. *Jeo face, par si que tu me doynes* — I do for this that you may give me. (Facio ut des: act in exchange for gift.)
4. *Jeo doyne, par si que tu me faces* — I give for this that you may do for me. (Do ut facias: gift in exchange for act.)
These four formulas map directly onto the classical Roman law categories of innominate contracts — bilateral obligations not falling within a named contract type — adapted here into the Law French of the early English common law. The formulas express the quid pro quo structure underlying a conveyance or obligation, identifying whether the consideration runs as gift-for-gift, act-for-act, act-for-gift, or gift-for-act.
Common Confusion
*Jeo done* is sometimes loosely grouped with *dedi* (the Latin "I have given," the standard operative word in a Latin feoffment deed) as though the terms are interchangeable. They are not. *Dedi* operates as a word of grant transferring property; *jeo done* in the Britton formulas operates as a statement of the causa or consideration-type, not as the word of conveyance itself. Conflating the two leads to misreading what a medieval instrument is doing at the moment the phrase appears.
Why It Matters in Research
Researchers encountering *jeo done* in manuscript or early printed sources should recognize it as operative conveyancing or pleading language, not mere narrative description. The phrase signals that the document is recording the type of consideration or cause underlying a transaction — critical for understanding whether the instrument creates a bilateral obligation and what performance is expected from each party.
The primary trap in historical sources is orthographic instability. Law French spelling was never standardized, and *jeo done*, *jeo doyne*, *je donne*, and variant forms all appear. Burrill notes that the readings cited derive from Wingate's edition of Britton — a secondary transcription layer — meaning researchers consulting the original Britton should expect additional variation and should not treat any single spelling as canonical.
The four-formula structure matters for connecting this term to the history of consideration doctrine. These formulas predate the common law's full development of consideration as a technical requirement for contract enforcement; they represent an earlier, more explicit typology of exchange. A researcher tracing the development of consideration from Roman innominate contract theory through the early common law will find *jeo done* formulas a useful signpost. Corpus connections run toward early treatise literature (Britton, Bracton), Year Book pleading, and early conveyancing precedents.
This term will appear almost exclusively in sources predating the seventeenth century. Post-Stuart legal writing had largely abandoned Law French in operative documents, and the phrase has no meaningful presence in modern practice.
Historical Dictionary Support
Burrill's Law Dictionary provides the primary English-language dictionary treatment, drawing on Wingate's edition of Britton (chapter 36) for the four bilateral formulas. Burrill's entry is essentially a transcription and translation exercise — it preserves the formulas and their English glosses but does not analyze their doctrinal function in depth. The entry cuts off mid-sentence in the surviving text ("These are the proposed readings of Wingate, in his edition of"), which suggests Burrill's discussion continued with cautionary notes about the reliability of Wingate's transcription. Researchers should treat the Wingate readings as one editorial layer removed from the original and consult independent editions of Britton where precision is needed.
No other major English legal dictionaries in the Law Mind shelf provide independent coverage of this term. Tomlin, Jacob, and Bouvier either omit it entirely or subsume it under general Law French glossaries without the bilateral formula structure Burrill preserves. This makes Burrill the essential starting point despite the truncation.
The broader Latin equivalents — *do ut des*, *facio ut facias*, *do ut facias*, *facio ut des* — are better covered in civilian and Roman law dictionaries and provide the doctrinal framework that the Law French formulas translate into the vernacular of early English practice.
