Cor-2 coro-, (core-). World English Historical Dictionary Dictionary Biographies Literary Criticism Welcome Terms of Service ⧏ Previous Next ⧐ Contents Slice Contents Key Bibliographic Record Murray’s New English Dictionary. 1893, rev. 2025. Cor-2 coro-, (core-) Gr. κόρη girl, doll, pupil of the eye (cf. BABY), has been taken as the basis of modern surgical terms relating to the pupil. The combining form of the Gr. word (as in other words in -η, -α) is κορο-, coro-, before vowels cor-; but core- representing the Gk. nom. case has by some been erroneously taken as the formative, giving the barbarous forms corelysis, coremorphosis, and the illiterate coreometer, coretodialysis, etc. Few of these combinations are English in form: the chief being Corectomy, Corotomy (core-), excision and incision of the pupil, Coroplasty (core-), an operation for forming an artificial pupil; Corectome, an instrument used in cutting through the iris; Coroplastic (core-) a., relating to coroplasty.
