CON words

[edda]

Is there a word to describe words that start with CON, such as CONcern, CONtain etc. Or describe the CON bit of the word??

[BobK]

It's a prefix, but not a productive prefix (by which I mean that people don't use it to make new words in English). I've never met a word that could be used to refer to them all, except something obvious like con- words!
