Prefixes are affixes added to the beginning of a word to modify its meaning, like "un-" in unhappy. Suffixes are added at the end of a word, such as "-ing" in running. Generally, adding a prefix or suffix doesn't change the original word's basic meaning significantly. However, there are rules for how specific prefixes and suffixes change the meaning or grammatical usage of a word. Understanding these rules can help you use prefixes and suffixes correctly to expand your vocabulary and communicate more effectively.
