Inflectional morphemes are affixes which carry grammatical meaning (for example, the plural -s in cats or progressive -ing in sailing). They do not change the part of speech or meaning of the word; they function to ensure that the word is in the appropriate form so the sentence is grammatically correct.
All inflectional morphemes in English are suffixes and are added after any derivational suffixes.
The most common inflectional morphemes are used in verb inflection (for example, ed in raced, -ing in racing, -s in races) but there are suffixes for noun inflection (for example, plural -s in horses and possessive -'s in Norma's) and adjective inflection (for example, comparative -er in faster and superlative -est in fastest).
Derivational morphemes are affixes which are added to a lexeme to change its meaning or function. They are used to make a new, different lexeme (for example, -ly changes the adjective sad into the adverb sadly).
Most derivational morphemes change the part of speech, for example, -ance changes the verb resemble into the noun resemblance. Note that the 'e' is deleted at the end of the verb resemble when the suffix is added.
--or--Morphology has two main subdivisions, namely inflection and derivation. Inflection deals with patterns of word structure that are determined by the role of words in sentences. Derivation creates new words with different meanings e.g., maltreat from treat.
