Very Low / TechnicalHighly technical/scientific (chemistry, metallurgy); Archaic (anatomy).
Definition
Meaning
The plural of 'calx', meaning the powdery residue left after the calcination of a metal or mineral; or, in older use, a heel or the heelbone.
In modern technical contexts, it refers to multiple substances (like oxides or ashes) produced by roasting or burning. In historical/anatomical Latin contexts, it can refer to multiple heels.
Linguistics
Semantic Notes
The word is a rare plural. Its meaning is entirely dependent on the specialized field. In contemporary English, it is almost exclusively found in historical scientific texts or very specific technical writing. The singular 'calx' is itself rare.

Connotations
Purely denotative; carries connotations of antiquity, alchemy, or precise laboratory science.
Frequency
Extremely rare in both. Slightly more likely to be encountered in British texts due to historical scientific literature.
