Then, use what you know about the meaning of the root words to guess the meanings of those words.

Although linguists sometimes divide the subject more finely, there are essentially three kinds of affix —the prefix, attached to the beginning as un- in unconscious , the infix , inserted in the middle, and the suffix , tacked on at the end as -ness, in consciousness. Note the lack of an example for infix. On the other hand, both prefixes and suffixes are highly productive derivational forms, constantly in use to form new English words.
A few of the most productive English prefixes are anti-, non-, pre-, re-, sub-, and un-.
