Editing Morpheme (section)

==== Derivational bound morphemes ====
* [[Derivation (linguistics)|Derivational]] morphemes, when combined with a root, change the semantic meaning or the [[part of speech]] of the affected word. For example, in the word ''happiness'', the addition of the bound morpheme ''-ness'' to the root ''happy'' changes the word from an [[adjective]] (''happy'') to a [[noun]] (''happiness''). In the word ''unkind'', ''un-'' functions as a derivational morpheme since it inverts the meaning of the root morpheme (word) ''kind''. Generally, morphemes that affix to a root morpheme (word) are bound morphemes.
