Not a word but a combination of two words. I really like to add 'n' for the 'a' even when I'm not supposed to. So for example, for the word animal, you'd say 'an' animal. But I also add the 'n' for a word like 'dog', so it would be 'an dog', or 'an cake'. Just to make it clear, I do it on purpose, I enjoy butchering languages!
Ripper666 agrees: Sometimes I have the same problem.
For some unknown reason, I can't ever seem to pronounce "multiplication" correctly when I say it out loud. It always comes out as "Multipliclaytion", sadly, no matter how many times I yell it, lol.
Also, I always say (and write) "clam down" instead of "calm down", but that's on purpose. 😀
