suffix definition and examples
A suffix is a letter or group of letters added at the end of a word which makes a new word. The new word is most often a different word class from the original word. In the table above, the suffix -ful has changed verbs to adjectives, -ment, and -ion have changed verbs to nouns. If you see a word ending in -ment, for example, it is likely to be a noun (e.g. commitment, contentment). Often, the suffix causes a spelling change to the original word. In the table above, the -e ending of complicate and create disappears when the -ion suffix is added. Other examples of spelling changes include:
