Need help establishing the type of formation

[hazzy]

Hi, I'm wondering about words like "labradoodle" (which has been formed by using parts of the words "labrador" and "poodle") or "escapator" (which has probably been formed by using parts of the words "escape" and "escalator"). What is their type of formation called? It's not really compounding, or is it?
Edit: also, what 'type of formation' is it if an ordinary word has been spelled in an alternative way, e.g., "quick" -> "kwik"? :/

"Labradoodle" and other words like it are called portmanteau words. I'm not sure what the changed-spelling words are called.

Aha, portmanteau words. Thanks a lot! :D
