does that word even exist??? (Kevin Riley)

Sometimes when i am eager to finish a paper, i tend to create my own words instead of thinking about how the sentence should actually be written. for example:

INCORRECT: The boy realized that he was a betterly trained athlete than everyone else.
CORRECT: The boy realized that his training was better than everyone else's.

INCORRECT: if she spoke better english, our conversations would be confuseless.
CORRECT: If she spoke better english, our conversations would be less confusing.

This only happens when i try to rush a sentence. if you read it too fast, you wouldn't even notice the mistake!!!!!
