When you are enamored by something or someone, you love it. It attracts you. You might say that you're enamored with your new car, or enamored of the new kid in school.
Enamor is a strange verb––it doesn't mean anything on its own. One cannot just enamor––that means nothing. One cannot even enamor something––that also is a meaningless proposition. Rather, you're enamored by the thing that attracts you. The verb is almost always used in a passive construction.
