In English, multiple words exist that are derived from κόλον, such as ''colectomy'',<ref name="Dirckx1997"/><ref name="Foster1891">Foster, F.D. (1891-1893). ''An illustrated medical dictionary.

A few compound words such as ''colonopathy'' have doublets with -on- inserted.<ref name="Dirckx1997"/><ref name="Dorland2000"/>
