Dictodelema

Dictodelema is when you are writing a word that you are fairly sure is spelt correctly (but not "correctly" unless that's actually the word you are having a dictodelema over if you know what I mean) but the word just looks wrong. You try spelling it about four other ways but they all look stupid. You look it up and you really did spell it right the first time, but it still looks wrong and you don't know why.
This also happens when you use a word so many times it loses all meaning. Try saying the word 'green' about thirty times. YO-HEAD-A-SPLODE!
