The main similarity between "The Purple Cow" and Frost's poem "Mending Wall" is that both use humorous language.
They don't use iambic pentameter, or blank verse, or strict meter, so these are not their similarities.
Explanation:
One way to use slang and idioms in a story is to make characters feel more natural and funny. Unless a character is very formal, real people would not talk without slang or idioms.
The choice of a character, persona, or a speaker affects the tone of a text by giving the text human quantities, or personification.
I am unsure if you have to have all of these letters in one word, but I will list a few words.
1: Off
2: Of
3: On
4: In
5: Coin
6: Fin
7: No
8: Nic
9: Onic
10: Icon
