A colleague of mine recently asked me a question for which I have not been able to find an answer, so, I thought I would consult the definitive experts on words.

I know there is a term for just about everything, but, this one has eluded me.
Perhaps I'm using the incorrect search parameters, but, it has to do with a particular vernacular whereupon the speaker will insert a word inside an otherwise complete word. An example might be, "Well, that's a-whole-nother issue", the word "whole" being inserted inside the word "another".

Is there a name for this construct? If not, perhaps there should be, since , at least in American English, it appears to be quite common.

Thanks,
