We often talk about the tool's it a poet's toolbox. Ideas like including two unrealted subjects, writing through senses, emotions, and observations.
A poet who writes in English can also take advantage of homophones and homonyms to stretch and bend meaning. They allow you to indluce a double entendre, letting a word inhabit two meanings. Hopmophones and homonyms also can provide hard pivot points in a poem
A homonym are words that sound alike but have different meanings. A homophone is a type homonym where the words have different meanings, different spellings, but sound the same.
Yesterday the #clmooc creww, inspired by Terry, wrote a series of homonym poems around the word fuse.
Fuse means many things. You can light a fuse, blow a fuse, or fuse things together. The etymologogical history maybe similar but the meaning different.
