The meaning of derivation and inflectional morphemes?

Derivation and inflectional morphemes are two types of morphemes in linguistics that are used to create new words or modify existing words.

Derivation morphemes are used to create new words by adding affixes to a base word. These affixes can change the meaning or part of speech of the base word. For example, adding the suffix "-er" to the verb "teach" creates the noun "teacher."

Inflectional morphemes, on the other hand, are used to modify existing words to indicate grammatical information such as tense, number, person, or case. These morphemes do not change the basic meaning or part of speech of the word. For example, adding the suffix "-s" to the noun "cat" creates the plural form "cats."

In summary, derivation morphemes are used to create new words, while inflectional morphemes are used to modify existing words for grammatical purposes.
