discuss the diffrence between inflectional and derivational morphology giving example
Inflectional and derivational morphology are the two major mechanisms ofthe language that add new forms and new lexemes by changing the words that serve as the basis for inflectional or derivational modifications. Inflectional morphology operates with grammatical forms and derivational morphology is used to derive new lexemes. For example, inflectional morphemes (underlined) in plays, played, playing, simplest are necessary to form the words that represent grammatical categories of the same part of speech, e.g. tense forms of the verb or degrees of comparison of adjectives. Derivational morphemes as an instrument of derivational morphology change the word class and, therefore, derive new lexemes: e.g. play – player. In this example,“player” as a lexeme derived from the name of action belongs to a different semantic class of agents. What we may see as one suffix represents, in fact, two different morphemes: -er in “clearer” is an inflectional morpheme while -er in “player” is the derivational one.
