Definition
An archaic adverb meaning "certainly," "surely," or "indeed." In historical legal texts, *wis* functions as an intensifier or affirmation — equivalent to modern expressions such as "surely" or "assuredly" — and appears occasionally in older pleadings, oaths, and formulaic legal language drawn from Middle and Early Modern English usage. It carries no independent technical legal meaning; its significance is purely linguistic, signaling emphasis or certainty in the surrounding statement.
Common Language
Modern common usage (Wiktionary): Certainly, surely; really, truly; indeed.
Historical common usage (Webster's 1913): "Certainly; really; indeed. [Obs.] 'As wis God helpe me.' — Chaucer."
The common and legal uses of this term are, for practical purposes, identical. *Wis* is not a term of art. Its appearances in legal sources are purely linguistic survivals of archaic English, not indicators of a distinct legal concept. Researchers encountering it in old documents should read it as a plain intensifier, not as a word carrying doctrinal weight.
Common Confusion
*Wis* is sometimes confused with *iwis* or *ywis*, variant spellings of the same word common in Middle English texts. All forms mean the same thing. Researchers should not treat variant spellings as distinct terms. Additionally, *wis* should not be confused with the verb *to wit* (meaning "to know" or used in the phrase "that is to say"), which serves a different grammatical and legal function in historical documents.
Why It Matters in Research
Researchers working in pre-eighteenth-century legal manuscripts, Year Books, early printed case reports, or ecclesiastical records may encounter *wis* as part of formulaic affirmations, oath language, or narrative pleading style. Its sole significance is as a marker of archaic English register, not as evidence of a legal standard or term of art. Misreading it as substantively meaningful — or conflating it with *wit* or *to wit* — can distort interpretation of the surrounding passage.
Burrill's inclusion of this term reflects the nineteenth-century lexicographic practice of cataloguing archaic vocabulary found in legal texts, ensuring practitioners and historians could parse older source material. Its presence in the dictionary signals that nineteenth-century lawyers still occasionally encountered the word in historical authorities they were expected to read and cite.
No jurisdictional variation is relevant. The term is uniformly obsolete across all common law jurisdictions.
Historical Dictionary Support
Burrill's Law Dictionary includes *wis* as a matter of linguistic completeness rather than doctrinal exposition. The entry in context — appearing alongside discussion of a wife's equity in chancery — suggests the term appeared in the surrounding source text as an archaic intensifier in narrative or formulaic legal prose, not as a term carrying independent meaning in that equitable doctrine. Burrill's treatment aligns with Webster's 1913, which marks the word as obsolete and illustrates it with Chaucer. Neither source attributes legal significance to the term beyond its plain meaning as an affirmation of certainty.
