Derivational morphemes

Derivational morphemes are identified when infixes combine with the root and changes either the semantic meaning.

Now, let's look at some examples:

  • Take the word unkind. In this word, un is a prefix and kind is the root. The prefix un acts as a derivational morpheme that changes the meaning of the word kind to its opposite meaning, unkind.
  • Take the word happiness. In this word, -ness is a derivational morpheme and happy is the root word. So, -ness changes happy to happiness. Check the POS tag, happy is an adjective and happiness is a noun. Here, tags that indicate the class of word, such as adjective and noun, are called POS.
