2. DEFINE MORPHOLOGY AND MORPHEME
• Morphology is the study of internal structure of the words while
a morpheme is the smallest meaningful unit in language
• For example, in the word ‘cats’, there are two morphemes. ‘Cat’
and ‘S’ of Plural. These two morphemes formed the word cats.
• But, in the word ‘category’, ‘cat’ is not morpheme because the
word ‘Egory’ is the preliminary of part of the word. So, the word
consists of only one morpheme.
•
3. • While in the word ‘categorize’, it is
• In ‘Categorized’ –
• Forget about how a word is spelled! Concentrate on what parts of theh word you
say carry meaning
Category + ize = cateogorize
Category + ize + d = categorized
Tip
Does the sum of the parts equal theh meaning of the
whole?
If yes, probably more thhan one morpheme. If no,
only one morphene

Overestimating Over + Estimate + Ing 3
Keyboard Key + board 2
Cranberry Cranberry 1
antidisestablishmentarianism Anti +di + establish + ment
arian + ism

Forthcoming Forth + come + ing 3
5. TYPES OF MORPHEMES
• Morphemes are of two types
1. Free morphemes
2. Bound morphemes
• Free morphemes divided into
• Lexical Morphemes
• Functional morphemes
• Bound morphemes divided into
• Derivational morphemes
• Inflectional morphemes
7. LEXICAL MORPHEMES
• Lexical morphemes – free morphemes that carry the content of our utterances.
• Lexical morphemes include
• Nouns
• Verbs
• Adjectives
• adverbs
• Lexical morphemes are opened class
8. FUNCTIONAL MORPHEMES
• functional morphemes – free morphemes that serve a more grammatical role,
connecting words together within and across sentences
• Functional morphemes include
• Prepositions
• Conjunctions
• articles
• They are closed morphemes
10. DERIVATIONAL MORPHEMES
• Derivational morphemes that help to create new words
and can change the lexical category of a word like the
affixes pre-, un-, -er, -ful
• For example, pre + determine = predetermine, in this
example, the prefix ‘pre-’, gives a meaning ‘before’ to
the stem word ‘determine’ while pre- never stands
alone.
• In teacher, teach + -er. The agentive –er, made the verb
‘teach’ noun. That is how works the bound morphemes
NOTE:
All prefixes in English are
derivational prefixes, but
not all derivational
morphemes in English
are prefixes
11. INFLECTIONAL MORPHEMES
• Inflectional Morphemes: bound morphemes that serve a grammatical role in
English like –d in deceived
• They cannot create new words in a language or change the lexical category of
a word in a language
• There are only 8 inflectional morphemes in English
13. SOME EXAMPLES
• Played = play + ed
• World’s = world + ‘s
• Wider = wide + r
• Largest = large + est
• Walking = walk + ing
• Driven = drive + n
• Books = book + s
• His = he + s
