Definition
An old English legal term referring to a person who deals in corn or grain — a corn merchant or grain trader. The term appears in medieval English legal sources as a variant form of *bladarius*, the more common Latin designation for the same occupation. As a legal designation, bladier identified an individual whose trade in grain could be subject to regulation, taxation, or restriction under manorial and market law.

Common Confusion
BLADIER vs. BLADARIUS vs. BLADUM: These three terms are closely related but distinct. *Bladum* (or plural *blada*) is the substantive noun — the grain or corn itself, whether growing, standing, or harvested. *Bladarius* is the standard Latin form for a grain dealer. *Bladier* is a variant, likely derived through Anglo-French influence, pointing to the same occupation. Burrill's entry for Bladier directs the reader directly to Bladarius, treating them as equivalent. Researchers encountering any of the three in a historical document are almost certainly dealing with the same underlying legal concept, but the specific form used may signal the document's linguistic register — Latin, Law French, or Anglicized vernacular.

Why It Matters in Research
This term is a navigational artifact more than a substantive legal concept. If you encounter *bladier* in a historical source, Burrill treats it as a simple cross-reference to *bladarius*, which is where the substantive legal content lives. Do not expect independent doctrine attached to this spelling variant.
The word matters in context because medieval grain trading was tightly regulated. Corn dealers could be subject to assizes of bread and ale, market regulations, forestalling and regrating prohibitions, and manorial customs governing how grain was measured and sold. The Magna Charta reference in the *bladum* entry (9 Hen. III, c. 25, concerning standard measures of grain) illustrates that grain commerce touched constitutional-level economic regulation in medieval England.
Researchers working in manorial records, market court rolls, or early borough custumals may encounter this term or its variants. When you do, the relevant legal framework is not a single doctrine but a cluster of overlapping regulatory regimes: assize law, market law, manorial custom, and forestalling statutes.
Spelling variation is a particular trap in this corner of the corpus. Medieval and early modern scribes rendered occupation-names inconsistently across Latin, Law French, and Middle English. *Bladier*, *bladarius*, *blader*, and *bledier* may all appear in sources referring to the same legal category of person. Index searches that rely on a single spelling will miss cognate forms.

Historical Dictionary Support
Burrill's Law Dictionary is the only source in the Law Mind shelf that contains this term, and Burrill treats it as a bare cross-reference: "See Bladarius." The substantive content is carried by the companion entries *Bladarius* and *Bladum*, both of which Burrill develops with citations to Bracton, Fleta, Spelman, and Magna Charta.
The Fleta citation (*lib. 2, c. 41, § 1*) and the Bracton references (*fol. 223b, 300b*) ground the term in thirteenth-century treatise law. The Magna Charta citation (9 Hen. III, c. 25) connects grain measurement directly to the foundational statutory tradition. No historical dictionary in the Law Mind corpus provides a more developed standalone entry for *bladier* itself — it exists in the record primarily as a pointer term.

Jurisdictional Note
This term is specific to the English legal tradition and has no direct American legal counterpart. It may appear in records relating to English colonial governance in early North America in contexts involving grain trade regulation, but such appearances would be antiquarian rather than doctrinally operative.
