Is there a term for a word that occurs unbroken within another word? For example, the word "fun" in "funeral", or "drag" in "hydragog".
The closest thing I could find from my search was the term "kangaroo word", which refers to a word that contains the letters of its synonym, in the correct order (though not necessarily consecutively).
I am currently using "substring" as a substitute in my essay. Unfortunately, "substring" applies to any selection of consecutive characters from the containing word, and doesn't convey the fact that the subset is a complete English word.
I have tagged this phrase-requests, but I would appreciate single words as well. I will have to use the term quite often, so the less awkward it is, the better.
