Types of Morphemes:

2-     Bound Morphemes: cannot occur alone in a sentence and they have to be attached to another morpheme.

 

Bound Morphemes are in 4 positions in a word.

2-     Suffixes: attach at the end of the free morpheme

3-     Infixes: attach inside a free morpheme

Root: cannot be divided

Stem: is like a host, it can be divided and accepts more morphemes

Word: is the final form, it can be divided but no morphemes can be added to it.

 

Why study morphemes?

We don’t know where one word starts and ends, only native speakers know, so we introduced morphemes.
