Quite a lot. In fact, the joke is that in English, any noun can be verbed. Some people abhor that, though, so try to use proper nouns/verbs/adjectives when you know them.
By the way, "abhor" is a strong word, so it is not used very often. People are more likely to use the word "hate" instead. Hate is normally a verb but is sometimes used as a noun, too ("His eyes were full of hate when he saw the potato."), though the correct noun for it is hatred.
