Definition
An ingrosser is an archaic variant spelling of engrosser — a person who engrosses, meaning one who copies a legal document into its final, formal form in a large, clear hand, or alternatively, in a commercial law sense, one who buys up large quantities of goods to gain a monopoly on their sale. The term carries both meanings that attach to engrosser; the spelling "ingrosser" is simply the older orthographic form and has no independent legal significance distinct from that parent term.
Common Language
Modern common usage (Wiktionary): Obsolete form of engrosser.
Because the common meaning here is simply a variant spelling with no independent semantic content, the gap between common and legal usage tracks entirely with the entry for ENGROSSER. Researchers encountering "ingrosser" in a historical source should treat it as a direct synonym and consult that entry for substantive analysis.
Common Confusion
Ingrosser and engrosser are interchangeable; the difference is purely orthographic and historical, not substantive. Researchers should not read any distinction in meaning into the differing spellings. Both forms also carry two analytically distinct senses — the documentary scrivening sense and the commercial monopolizing sense — that should not be conflated with each other. Context in the source document will usually make clear which sense is operative.
Why It Matters in Research
Ingrosser appears almost exclusively in early English legal texts and the commentators who drew on them — Cowell, Blount, and the tradition of legal lexicography that followed. Because the spelling "ingrosser" dropped out of use well before the nineteenth century, a researcher will encounter it mainly when working with pre-modern English statutes, plea rolls, or the antiquarian dictionaries that preserved archaic terminology. When searching Law Mind corpus sources, queries for "engrosser" will not automatically surface documents using only the "ingrosser" spelling; both search terms should be run if working with sources predating 1700. The commercial-monopoly sense of the term connects to a body of English statutes against forestalling, regrating, and engrossing — offenses that were prosecuted seriously in Tudor and Stuart England and were still discussed in eighteenth-century treatises, though largely abolished as statutory crimes by the early nineteenth century. A researcher focused on the documentary-copying sense will find the term relevant to conveyancing practice and the office of the engrossing clerk in Chancery.
Historical Dictionary Support
Burrill's Law Dictionary, the sole shelf source treating this term directly, defines ingrosser as "an old form of engrosser, used by Cowell and Blount," and refers the reader immediately to the entry for Ingross. This is consistent with the treatment in other historical dictionaries, which handle the substantive content under engrosser or engross and note the variant spelling only in passing. Cowell's Interpreter and Blount's Law Dictionary — the seventeenth-century lexicons Burrill cites — were themselves drawing on even earlier usage, reflecting the period when the "in-" prefix spelling was still current in English legal writing. No historical source assigns ingrosser any meaning not also carried by engrosser; the historical dictionaries are uniform on this point, and there is no divergence worth flagging.
