Some of the tools poets use in their writing is emphasis and feeling. Like how colors look different in somebody else's perspective. They take their opinions and thought into their writing and make it into poetry. It can also be used to express other things like hate and love. Some can be random. Many have to be explained to get what the poet is saying. Most are comical and annoying. They use new and weird words and some put normal words. Like "Jabberwocky" by Luis Carroll. He made up words that could be interpreted in different ways. Those are some of the things poets use.
