Definition
In old English law, an addition to a name. Adjection referred to the appending of a descriptive word, title, or designation to a person's name — for example, a trade, rank, or place of origin — used to distinguish individuals who shared the same given name or surname. The practice was closely tied to the formal requirements of pleading and record-keeping, where precision in identifying parties was legally consequential.
Common Language
Modern common usage (Wiktionary): The act of adjecting or adding, or the thing added.
Historical common usage (Webster's 1913): The act or mode of adding; also, the thing added.
The common meaning is a general term for any act of addition. The legal meaning is narrower and specific: adjection concerns additions to personal names in a formal legal or record-keeping context, not addition in the abstract sense. A researcher encountering the term in a legal source should not read it as referring to additions to documents, property, or arguments — it pertains to nomenclature and the identification of persons.
Why It Matters in Research
Adjection is a term of narrow historical significance, confined almost entirely to early and medieval English common law pleading practice. Researchers working in Year Books or early plea rolls will encounter it as part of the formal conventions governing how parties were named and identified in legal proceedings. Getting a name wrong — or failing to distinguish one John from another — could be fatal to a writ or plea in the formalistic pleading system of the period, which gives the concept its legal weight even if the word itself rarely appears in later sources.
The term does not survive meaningfully into modern legal usage. Its appearance in secondary or treatise literature is almost always retrospective, describing historical practice rather than any living doctrine. Researchers should treat it as a term of art for medieval English procedure and not expect to find it operative in post-medieval statutory or equity materials.
One navigational trap: the common meaning of "adjection" as simple addition might lead a researcher to misread early sources as referring to additions to documents or pleadings generally. In legal context, the word consistently attaches to names and personal identification, not to instruments or arguments.
Historical Dictionary Support
Burrill's Law Dictionary identifies adjection as a Law French term from old English law, defining it as "addition to a name," and cites Year Book Michaelmas Term, 9 Edward III, folio 40 as authority. This places the term firmly in the early fourteenth century and in the Year Book tradition. Burrill's entry is brief, which accurately reflects the term's narrow scope — it was never a term of broad doctrinal significance but rather a technical label for a procedural convention.
No other major historical dictionaries in the Law Mind corpus appear to cover this term. Given the term's limited reach, the absence of treatment in later dictionaries like Black's early editions is consistent with its obsolescence by the time those works were compiled. Researchers relying solely on more recent dictionaries will find no entry and should understand that silence as confirmation of the term's archaic status rather than as a gap in coverage.
