short noteon Derivational suffixes

Answer 1

Derivational suffixes are used to make (or derive) new words. In particular, they are used to change a word from one grammatical class to another. For example, the noun "pore" can be changed into an adjective by adding the suffix -ous, resulting in the adjective "porous" 'having pores'.

Answer 2

Derivational morphology basically involves two general processes, affixation and compounding. There are derivational affixes just as there are inflexional affixes, and many lexemes in many languages are formed by affixation. One of the most important things to understand about derivational morphology, as opposed to inflexional morphology, is that derivational morphology can significantly change the words it plays around with not only in form but in meaning and category.
