Inflection & Derivation Question

Hi, Everyone,

I am reading about morphemes to understand word classes and wanted to see if my current understanding is correct.

The word "fat" can be an adjective (1) or a noun (2):

  • (1) The fat man; or
  • (2) The man liked to eat fat.

If I make (1) "fatter", this is an example of inflection (same word class).

In contrast, while not a grammatical sentence if you make (2) "fatter", this would be an example of derivation due to a change in word class.

Am I on the right track with my understanding?

Many thanks,
