Definition
Retallia is a term from old English law denoting retail trade — that is, the division or cutting of a commodity into smaller parts for sale, as distinguished from sale in gross (wholesale). The term describes the mode of selling goods in small quantities directly to end purchasers rather than in bulk to merchants or middlemen.
Why It Matters in Research
Retallia appears almost exclusively in very early English legal sources and in formulaic Latin pleading language. Researchers encountering the term will find it most often in writs, register entries, and records governing trade privileges, guild rights, and market regulations in medieval and early modern England. The phrase nec in grosso, nec ad retalliam — neither in gross nor at retail — appears in the Registrum Omnium Brevium and signals a complete prohibition on commercial sale of a particular commodity, a construction that carries legal weight beyond its simple components.
The term has no meaningful survival in modern legal usage. Because it belongs to the Latin-French hybrid layer of medieval English legal vocabulary, it can be easily missed by researchers searching only English-language indexes. It may appear in licensing instruments, letters patent, and borough charters governing trade monopolies, where the distinction between wholesale and retail rights was legally significant and commercially consequential.
Do not expect to find retallia in American sources. It is a term of English origin that did not migrate into colonial or early American legal usage with any currency.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in complete agreement on the definition: retail in the old English legal sense, derived from the Law French retailler (to cut again), signifying subdivision of a commodity for small-scale sale. Burrill adds the instructive quotation from the Registrum Omnium Brevium — nec in grosso, nec ad retalliam — which illustrates actual usage in writ practice and anchors the term in a specific documentary tradition. Neither source elaborates on the legal consequences of selling at retail versus in gross, which in medieval trade law could determine guild jurisdiction, tax liability, and the applicability of market regulations. The brevity of both entries accurately reflects the term's narrow historical footprint.
Jurisdictional Note
Retallia is a term of English medieval and early modern law with no recognized presence in Scottish, Irish, or American legal traditions. Its relevance is confined to English sources, primarily before the eighteenth century.
