A typo is a spelling error produced by careless typing. Leaving these in your fic is a sure sign that you didn't engage the services of a beta-reader.
Typos of a canon name turn into a different Mini based on which continuum the name was from.
In OFUM and on the PPC Board, typos may be blamed on Toey, the One Toe Ring of Causing Typos. Damn you, Toey!
