Word Formation Process:Derivation

What is derivation as a word formation process??? 

 Derivation: Is a word formation process that attach derivation affixes to the main word/form to create a new word.

 In broad sense, it is the formation of words by changing the form of the base or by adding affixes(prefixes&suffixes) to it. 

For word, to which we attach affixes. These affixes are usually described as prefixes and suffixes and they are not usually listed separately in dictionaries. 

Such affixes usually apply to words of one lexical category (part of speech) and change them into words of another such category.

Some common examples include un-, dis-, mis-, -ness, -ish, -ism, -ful and -less, as in words like unkind, disagree, misunderstand, kindness, childish, behaviourism, useful and useless. We call the word form created by the addition of a derivational morpheme a derived word. The next two pictures contain typical examples of English derivational pattern and their affixes.
