Suffixes go at the end of words. A suffix always changes the meaning of the root word. It sometimes changes the part of speech as well.

Do suffixes have the same meaning?

Different prefixes, roots, or suffixes may have the same meaning. For example, the prefixes bi-, di-, and duo- all mean “two.” 6. Sometimes you may identify a group of letters as a prefix or root but find that it does not carry the meaning of that prefix or root.

What is the suffix rule?

When you add a suffix to a word which ends in a consonant followed by a 'y', change the 'y' to 'i'. e.g. The word 'happy' ends in 'py'. When you add the suffix 'ness', change the 'y' to 'i' to make the word happiness: happy + ness = happiness. Exceptions to the rule.
