Question

What is the difference between a prefix and a suffix

Answer 1

A prefix comes before the word, such a sub- and pre-, and suffix would be after, like -all and -some. There's a ton of prefixes and suffixes though.

Answer 2

a SUFFIX is a word part added to the end of a word (for example, -ful). If you add the suffix -ful to the base word, help, the word is helpful.

a PREFIX is a word part added to the beginning of a word or base word (for example, un-). If the prefix un- is added to helpful, the word is unhelpful.
