what is suffixes and affixes

Answer 1

an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed.
A suffix is a letter or a group of letters attached to the end of a word to form a new word or to change the grammatical function (or part of speech) of the original word
