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 "G."
Genius
Ghoulish
Gingerly
Glaring
Glorious
Gobsmacked
Gorge
Grainy
Gratitude
Gremlins
