Dear (insert word),
Thanks for occurring to me as an option. The possibilities within the meaning and implication (insert word) offers intrigued me as both a poet and a reader. Unfortunately, I will not be including the connotation it implies. (Insert word) does not fit the theme or intention motivating my poem in it’s current form.
Once again, I’d like to express gratitude on behalf of my poem for the suggestion. I regret that I was unable to find a purpose for (insert word) in my work.
My best wishes in securing placement in a future poem. I will retain the word for use in my vocabulary. Bear in mind, this is not a judgement on the quality or value of (insert word). I may reconsider should on-going revisions reveal a benefit in the use of the term.
(Insert a form of the word as a backhanded pleasantry)
