You know when you say or look at a word so many times that it doesn't look like a word any more? Well there's actually a name for it. It's called (thanks Wikipedia) "Semantic Satiation".
The technical definition is "a cognitive neuroscience phenomenon in which repetition causes a word or phrase to temporarily lose meaning for the listener, who can only process the speech as repeated meaningless sounds". Reading on in the Wikipedia page, this is used to help people with some kinds of stutters because it stops them associating certain words with particular emotions.
I don't want to live in a world without Wikipedia.
