Affixes are forms that are attached to words or word elements to modify meaning or function. According to the functions of affixes, we can put them into two groups; inflectional and derivational affixes.
Affixes attached to the end of words to indicate grammatical relationships are inflectional, thus known as inflectional morphemes. The number of inflectional affixes is small and stable.
Derivational affixes. As the term indicates, derivational affixes are affixes added to other morphemes to create new words. Derivational affixes can be further divided into prefixes and suffixes. Prefixes come before the ward and the suffixes after the word.
9 - A root is the basic form of a word which cannot be further analysed without total loss of identity. The root, whether free or bound, generally carries the main component of meaning in a word. Root is that part of a wordform that remains when all inflectional and derivational affixes have been removed.
10 - A stem may consist of a single root morpheme as in iron or of two root morphemes as in a compound like handcuff. It can be a root morpheme plus one or more affixational morphemes as in mouthful.
A stem can be defined as a form to which affixes of any kind can be added.
