the prefix and suffix
A prefix is a letter or group of letters added to the beginning of a word to make a new word: In the word '”UNHAPPY”, 'UN-' is a prefix added to HAPPY. UN- is a Latin word for NOT.
A suffix on the other hand is a letter or group of letters added to the end of a word to make another word. The suffix NESS added to the end of the word TOGETHER creates another word TOGETHERNESS. A good knowledge of English prefixes and suffixes will help students develop vocabulary without the need to always check their dictionary. Also a brief lesson to adult intermediate students about the etymology of English words can help a great deal..
