AFFIXES
An affix is a morpheme that is attached to a word stem to form a new word. Affixes may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed. They are bound morphemes by definition; prefixes and suffixes may be separable affixes. Affixation is, thus, the linguistic process speakers use to form different words by adding morphemes (affixes) at the beginning (prefixation), or the end (suffixation) of words.
TYPES OF AFFIXES
PREFIX-A prefix is an element placed at the beginning of a word to adjust or qualify its meaning, for example de-, non-, and re-. Example of prefixes: Forming verbs and their derivatives. Deinstall- (removal a piece of computer software from a system)
Demutualize- (change the status of a mutual organization such as a building society to a different kind).
Delayer- (to reduce the number of levels in an organizational hierarchy of employees)
2.A very few further examples in various senses are: (non-not)
This prefix is more widely used to form negatives than any other. non-believer, non-fattening,non-negotiable,non-partisan, non-returnable, non-smoking, non-stop, non-uniformly, non-violent.
3.In principle, re- can be added to any verb to make new verbs or verbal derivatives. The most commonly encountered sense, especially in words of modern creation on English stems, is of something happening or being done once more or afresh: redecorate, re-elect, repeat, re-roof, reprint, retry, rewrite.
SUFFIX-A suffix is an element placed at the end of a word to form a derivative, such as -ation, -fy, -ing, frequently one that converts the stem into another part of speech. –ation- An action, or an instance of an action.
Ex.creation, deviation, moderation, navigation, perforation,pronunciation,suffocation, vibration
-fy Also ify- Make or produce; transform into; become.
