4.1 Derivation

Derivation creates a new word by changing the category or the meaning of the base to which it applies, e.g., teach (v)+ er (suffix) = teacher (n); beauty (n)+ful (suffix)=beautiful (adj).

Derivation is a productive means of coining new words in English; there are over sixty common derivational affixes, and there is no limit to their number.

Each line in this table can be considered a word-formation rule, which predicts how new words may be formed. Thus, if there is a rule whereby the suffix –ment may be added to the verb achieve, resulting in a noun, denoting the act or result of achieving, then we can predict that if the suffix –ment is added to certain verbs, the result will be a new noun.

These rules may be used to analyze words as well as to form new words. Derivation can also create multiple levels of word structure. Although it may seem complex, correctional, unkindness, and organizational have structures consistent with the rules given in the Table.

un kind ness

In the example with the word unkindness, the observation here is that the prefix un- readily combines with adjectives before it converts to a noun. We see from these examples that complex words have structures consisting of hierarchically organized constituents.
