• Derivation : it is accomplished by means of a large number of small
“bits” of the English language which are not usually given separate
listings in dictionaries.
• Prefixes and suffixes : we can see that some affixes have to be
added to the beginning of the word (e.g. un-, mis-). These are called
prefixes Other affixes have to be added to the end of the word
(e.g. -less, -ish) and are called suffixes.
