Definition
Meaning
A cup-shaped structure, cavity, or receptacle; in botany, the whorl of sepals forming the outer part of a flower; in anatomy, a cuplike extension of the renal pelvis.
The term extends metaphorically to describe any chalice-like form in architecture (e.g., the calyx of a Corinthian capital) or in technical descriptions of cup-like objects in various scientific fields.
Linguistics
Semantic Notes

Frequently Asked Questions
They are variant spellings of the same word, with 'calyx' being significantly more common, especially in botany. 'Calix' is an accepted but less frequent spelling.
No. It is a specialised term used almost exclusively in scientific (biological, medical) and certain technical (architectural) contexts.
The traditional and most technically correct plural is 'calices' (pronounced /'kælɪsiːz/). The regularised plural 'calyxes' (or 'calixes') is also found but is less preferred in formal technical writing.
Historically, it comes from the Latin for 'cup', but in modern English, it has lost that general meaning. For a drinking cup, use 'chalice', 'goblet', or 'cup'.
