You clearly don't have a good grasp on the English language if you don't agree with me that his use of the word "of" in this sentence is incorrect ND.

You also don't understand what a "typo" is.

Let me explain it to you: a typo (typographical error) is when an incorrect key is struck when typing. Typing the wrong word completely is not a typo.

Hitting a 2 instead of a 3 when entering a number, for example, COULD be a typo.
