I am still looking for title words to add to one of my current projects. I cannot guarantee your word will be chosen for the theme of a poem, but if it is, I will give proper acknowledgement when the book is published.
Here are the current title words for the letter "M."
Magnetic
Meager
Mellifluous
Memoriter
Memorize
Mensch
Mercy
Mighty
Mild
Miraculous
Mnemonic
Moggy
Mosaic
Mumpsimus
Mushroom
Mystery
