Common Prefixes and Suffixes: A Quick Reference Guide 

Prefixes and suffixes are important components of the English language. Prefixes are added to the beginning of a word and change the meaning of the word, while suffixes are added to the end of a word and also change its meaning. For instance, the prefix ‘un’ can be added to the word ‘happy’ to make it ‘unhappy’ and the suffix ‘-ly’ can be added to the word ‘quick’ to make it ‘quickly’. Knowing how to use prefixes and suffixes correctly can help to improve a person’s understanding of the English language and help them to become more proficient in their writing.
