(1988) says that derivational morphemes are bound
morphemes which derive (create) new words by either changing the meaning or the part of speech or both. Bound
morpheme = those that function only as parts of
words ( can’t stand on its own ) For
example : doubtful , establishment , frighten, teacher
The
underscore part = bound morpheme

Another examples : • In the word happiness, happiness, the bound morpheme – ness creates a new word by changing both the
meaning and the part of speech. • Happy = adjective • The derived word happiness = noun.
A
similar process uses prefixes instead of suffixes
In
English, prefixes typically change the meaning of a word but do not alter its lexical category. Example : a. MIS- + Verb Verb ( misstep, misclassify ) misclassify ) b. UN- + Adjective Adjective ( unkind, untrue, unfair ) unfair ) c.
UN- + Verb Verb ( undo, unchain, uncover ) uncover )
Some
derivational
morphemes
create
new
meaning but do not change the syntactic category or part of speech. The word unhappy, for example, consists of the base happy and the derivational morpheme (prefix) un-. Happy The
= adjective
derived word unhappy is also an adjective. adjective.
In
English, such derivational morphemes tend to be added to the ends of words as suffixes The meaning changes and The relationship can be represent as follow : a.
Adjective ( beautiful, Noun + -ful doubtful ) b. Adjective + -ly Adverb ( truly, beautifully ) beautifully ) c. Verb + -ment amazement ) Noun ( amazement ) d. Verb + - er rider ) Noun ( teacher, rider ) e. Adjective + -en Verb ( brighten, harden ) f. Noun + -en Verb ( frighten, hasten )
d.
UNDER- +verb Verb ( undercount,
underscore ) e. RE- + Verb Verb ( rephrase, rewrite ) f. EX- + Noun Noun (ex-husband, (ex-husband, ex – wife )
