Malapropism

A malapropism is a misused word. A spoonerism is a mispronounced word, when you transpose letters or sounds. For example, "noosperism" would be a spoonerism of spoonerism.

So, I'm trying to figure out what is the appropriate term for George Bush saying "nucular" instead of "nuclear." It is not a spoonerism, but it is mispronounced. Where did the extra "u" sound come from in the middle?


Note on last blog: thingamabob and thingamajig are in my dictionary. Watchamacallit is not. I wonder if these are regional expressions?
