EINS CEO QUE

Definition

A Law French phrase meaning "in this that" or "inasmuch as." Used in medieval English legal texts as a connective or qualifying particle, introducing a condition, limitation, or circumstantial clause within a pleading or legal instrument. The phrase does not carry independent substantive legal meaning but functions grammatically to link or subordinate one legal proposition to another.

Why It Matters in Research

This term is encountered almost exclusively in transcriptions of medieval English legal records, Year Books, and early treatises written in Law French — the technical legal dialect of English courts from roughly the Norman Conquest through the seventeenth century. Researchers working in those sources need to recognize it as a grammatical connector rather than a term of art with doctrinal weight. The principal trap is mistranscription. Law French manuscripts are frequently difficult to read, and scribal abbreviations make "eins ceo que" easy to misread or to confuse with adjacent phrases. Kelham's glossary, cited by Burrill, lists multiple English translations for the phrase — "when," "unless," "the same," "rather," "until" — a spread wide enough to signal that medieval scribes and compilers used the phrase loosely. Context within the surrounding clause is therefore essential to determining which English equivalent is intended. A researcher who defaults to a single mechanical translation risks misreading the legal effect of the provision entirely. Because the phrase appears in sources such as Britton (the thirteenth-century treatise cited by Burrill at chapter 54), researchers consulting early printed editions of that work should be aware that later editorial hands sometimes silently modernized or dropped Law French connectives, which can alter the conditional structure of the original passage.

Historical Dictionary Support

Burrill's Law Dictionary is the principal English-language legal dictionary source to address this phrase, and its treatment is brief: the Latin French origin, a citation to Britton, and Kelham's range of translations. The entry immediately following in Burrill — covering EIRE / Eyre — is unrelated and should not be read as continuation of the same definition, though it appears in the same passage of source text. Burrill does not assign the phrase a specific doctrinal function beyond its grammatical role, which is consistent with the phrase's nature as a connector rather than a substantive legal concept. No major English law dictionary of the nineteenth or twentieth century gives the term significant independent treatment. Its absence from later dictionaries reflects the general obsolescence of Law French in legal practice rather than any uncertainty about its meaning.

Jurisdictional Note

Relevant only to the historical common law of England and jurisdictions whose early legal records were maintained in Law French. Of no operative significance in any modern jurisdiction.
