Prejudice

“He is not the best person for the position, but his many kindnesses to me prejudice me in his favor.” We may be prejudiced against a person or thing, but cannot be prejudiced in favor. Use predispose.

Preventative

The correct form of the word is preventive, not preventative.

Previous, Previously
