* New ones are constantly being created: Language is dynamic. New words, and therefore new prefixes and suffixes, are constantly being coined.
* Some are debatable: There's not always a clear line between what's a true prefix/suffix and just a part of a word.
However, we can talk about the general idea:
* Prefixes: There are hundreds of common prefixes in English, adding meaning to the beginning of words (e.g., "un-", "re-", "pre-").
* Suffixes: Similarly, there are hundreds of common suffixes, changing the function of words (e.g., "-ing", "-ly", "-ment").
If you want to learn more about prefixes and suffixes, consider these resources:
* Dictionaries: They usually include lists of prefixes and suffixes, with examples.
* Grammar books: These often have sections dedicated to prefixes and suffixes.
* Online resources: Many websites offer lists and explanations of prefixes and suffixes.
Remember, the key is to understand how they function and their common meanings.
