Linguistic Note

The word conchoid derives from the Latin concha, which means mussel.

Ultimately the word derives from the Ancient Greek κόγχη (kónkhē) plus -oid, or directly from Ancient Greek κογχοειδής (konkhoeidḗs), which refers to anything with the general shape of a mussel shell.

It is properly pronounced kon-khoid, where the kh sound is the one found in the Scots loch or German ich.

However, it is commonplace to use the pronunciation kon-koid.

Note that the pronunciations kon-tshoid and kon-shoid are technically incorrect.
