Inflectional morphemes are bound morphemes which are not used to produce new words in the language , but rather to indicate aspects of the grammatical function of a word.
Inflectional morphemes are just used to show if a word is plural or singular, if it is past tense or not, and if it is a comparative or possessive form .

DERIVATIONAL MORPHEMES The basic concept of derivational morphemes is that they derive new words.
In the following examples, derivational morphemes are added to produce new words which are derived from the „parent word‟ (root). happy – happiness (adjective) (noun) beauty – beautiful – beautifully (noun) (adjective) (adverb) danger – dangerous (noun) (adjective) In all cases, the derived word means something different than the root, and the word class may change with each derivation.

Derivation does not always cause the change of word class; but in such a case, the meaning of word will usually be significantly different from the root. Examples: visible – invisible (Adjective) (Adjective) create – recreate Different meaning from the root (different (noun) (noun) category) but still in the same word classes. market – supermarket (noun) (noun) terminate – determinate (verb) (verb)
