What is suffix & prefix

In English grammar, a prefix is a group of letters added to the beginning of a word to modify its meaning. Similarly, a suffix is a group of letters added to the end of a word to modify its meaning. Both prefixes and suffixes can change the meaning of a word, and they are important for understanding and using English vocabulary effectively.

Here are some examples of common prefixes:

• "un-" (meaning "not" or "opposite"): unhappy, unsure, unkind
• "re-" (meaning "again" or "back"): return, rebuild, refresh
• "pre-" (meaning "before"): preview, prefix, preheat
• "dis-" (meaning "not" or "opposite"): disagree, disappoint, disapprove

And here are some examples of common suffixes:

• "-able" (meaning "able to be"): readable, comfortable, understandable
• "-ful" (meaning "full of"): joyful, thankful, successful
• "-ness" (meaning "state or quality of"): happiness, kindness, boldness
• "-ment" (meaning "act or process of"): movement, agreement, statement

Adding a prefix or suffix can change the meaning of a word in a variety of ways. For example, adding "un-" to "happy" creates "unhappy," meaning "not happy." Adding "-able" to "read" creates "readable," meaning "able to be read." Adding "-ful" to "joy" creates "joyful," meaning "full of joy."

It's important to note that prefixes and suffixes can also affect the spelling and pronunciation of a word. For example, when the prefix "re-" is added to the word "build," it changes the spelling to "rebuild." Similarly, when the suffix "-ment" is added to the word "agree," it changes the pronunciation to "agreement."

Overall, prefixes and suffixes are an important part of English grammar and vocabulary. By understanding the meanings and usage of common prefixes and suffixes, you can expand your vocabulary and communicate more effectively in English.
