Cornean

Cornean is an infrequently used English term that can function as an adjective or, less commonly, as a proper noun. It historically traces to the Latin cornu, meaning horn, and follows the English suffix -ean to indicate relation or origin. Because cornean is not widely attested in modern dictionaries, its exact meaning tends to be determined by context and can be ambiguous.

In historical scientific literature, cornean has occasionally been used to describe horn-like structures or materials, including keratinized surfaces or other horn-bearing tissues. In contemporary biology and medicine, more precise terms are preferred. For describing the eye, the standard adjective is corneal, not cornean. When referring to horn-related tissues in animals or plants, terms such as cornual, cornified, or corneous are typically used, depending on the tissue and taxonomic group.

Beyond scientific writing, cornean may appear as a rare toponymic or family name in some languages, though such uses are uncommon in English-language references. Because cornean is not part of standard terminology, readers should verify its meaning from the specific source in which it appears and, when precision is required, opt for established terms such as corneal, corneous, or cornual.
