The document outlines two main types of morphology: free morphemes, which include lexical morphemes that convey meaning and functional morphemes that assist in grammatical structure, and bound morphemes, which consist of inflectional morphemes that modify words without changing their grammatical category, and derivational morphemes that create new words with different meanings or grammatical categories. It provides examples of each type of morpheme and clarifies the distinctions between inflectional and derivational morphology. This information is essential for understanding word formation and grammatical structure in linguistics.

1. Types of Morphology

3. Categories of free morphemes
1. Lexical morphemes
Morphemes that carry the content or meaning of the messages that we are
conveying.
In order to identify a lexical morpheme, ask yourself this: “If this morpheme was
deleted, would I not be able to understand the main message of this sentence?” If
the answer is yes, then you have a lexical morpheme.

4. Examples of lexical morphemes:
follow, type, look, yellow, act, pick, strange

5. 2. Functional morphemes
Morphemes that do not carry the content of a message, but rather help the
grammar of the sentence function.
These free morphemes can be identified by asking yourself this question: “If this
morpheme was deleted, would I still be able to understand the main message of
this sentence?” If the answer is yes, then you have a functional morpheme.

6. Examples of functional morphemes:
but, when, near, above, in, the, that, them, if

7. Categories of Bound Morphemes
1. Inflectional Morphemes
An inflectional morpheme is a suffix that’s added to a word to assign a particular
grammatical property to that word, such as its number, mood, tense, or possession.
Inflectional morphology is the study of the processes that distinguish the forms of
words in certain grammatical categories. This includes processes such as affixation
and vowel change, which create inflectional morphemes.

8. However, an inflectional morphology can never change the grammatical category of
a word. You can add an inflectional morphology to a verb, noun, adjective, or an
adverb.
For example:
• adding a ‘-s’ to the verb plural verb ‘run’ can make this verb singular (runs).
• adding ‘-ed’ to the verb dance creates the past tense of the verb (danced).

10. • inflectional morphemes usually produce different forms of the same word, instead
of different words.
• In addition, inflection does not generally change the basic meaning of a word as
they only add specifications to a word or emphasize certain aspects of its
meaning.
• Thus, words under inflectional morphology are not found as separate entries in
dictionaries.
Thus,

11. 2. Derivational Morphemes
A derivational morpheme is an affix we add to a word in order to create a new word
or a new form of a word.
Derivational morphology is the study of the formation of new words that differ
either in syntactic category or in meaning from their bases.
Moreover, a derivational morpheme can either change the meaning or the
grammatical category of the word.

12. For example:
Change in Meaning
• Leaf → Leaflet
• Pure →Impure
Change in Grammatical Category
• Help (verb) → Helper (noun)
• Logic (noun) → Logical (adjective)

14. • Unlike inflectional affixes, derivational affixes can be both, prefixes or suffixes in
English.
• derivational morphemes change either the meaning or the category of the original
words, forming new words.
• These words are found under new entries in dictionaries.
Thus,

15. The key difference between inflectional and derivational morphology is that the
inflectional morphology deals with the creation of new forms of the same word
whereasthe derivational morphology deals with the creation of new words.
