Definition
Approperment is an archaic Law French term with two related senses recorded in early legal usage: (1) properly or appropriately, functioning as an adverb or qualifier in legal instruments; and (2) appropriation — the act of setting apart or assigning something to a particular use, person, or purpose. The term appears almost exclusively in historical English legal texts and is not in active use in modern legal practice.
Common Confusion
Approperment and APPROPRIATION are functionally equivalent when approperment is used as a noun. Researchers should not treat them as meaningfully different concepts. The risk of confusion runs in one direction: a researcher familiar with appropriation may fail to recognize approperment as its synonym and either misread the older term or fail to connect it to the relevant body of doctrine. There is no corresponding risk of conflating approperment with any modern term, since the word is entirely out of use.
Why It Matters in Research
Researchers encountering approperment in pre-modern English legal documents — particularly those written in or influenced by Law French — should treat it as a variant or precursor form rather than a distinct legal concept. Its dual sense as both an adverbial qualifier and a noun synonym for appropriation means that context governs interpretation entirely. A phrase using approperment to mean "properly" reads differently from one using it to mean "an appropriation," and mistaking one for the other could alter the meaning of an instrument or record significantly.
The practical research consequence is narrow but real: approperment is unlikely to appear as an index term or headword in secondary finding aids, case digests, or modern treatises. Researchers who encounter the term in primary sources — plea rolls, early conveyances, ecclesiastical records, or Year Books — will need to resolve its meaning from surrounding text. Burrill's remains one of the few reference points that acknowledges the term at all. Kelham's Glossary of Norman and Old French Law Terms (the "Kelham" cited by Burrill) is the deeper source and should be consulted for fuller philological context.
Because approperment shades directly into appropriation, any document in which it appears as a noun is likely dealing with the same subject matter that would later be addressed under the vocabulary of appropriation: assignment of tithes to a religious house, allocation of property to a designated purpose, or the formal dedication of an asset to a specific use. Researchers should follow threads under APPROPRIATION in both legal dictionaries and historical sources to develop the substantive law.
Historical Dictionary Support
Burrill's Law Dictionary provides the only significant headword treatment of approperment in the Law Mind corpus. Burrill offers two glosses — "Properly" (citing Kelham) and "Appropriation" (also citing Kelham) — without further elaboration. The entry is essentially a relay to Kelham rather than an independent analysis.
The brevity of Burrill's entry reflects the term's status as a philological curiosity rather than a live doctrinal concept even at the time of Burrill's writing. No definition is offered because none is needed for practicing lawyers; the entry exists to assist those reading old texts. Other major historical dictionaries — Jacob's Law Dictionary, Tomlin's Law Dictionary, Bouvier's Law Dictionary — do not appear to carry the term as a headword, which itself confirms its marginal status.
What Burrill and Kelham together establish is sufficient: the term is Law French in origin, it operates at the intersection of ordinary language (properly) and legal concept (appropriation), and it should not be treated as carrying independent doctrinal weight distinct from appropriation.
