* "Something you say to pest" could be a few things, like "shoo," "go away," or "buzz off."
* "Covering foot" likely refers to a "sock."
The homophone (a word that sounds the same but is spelled differently) would depend on which word you chose for the first part.
Here are some possibilities:
* "Shoo" and "sock" - There's no direct homophone here, but "shoo" and "sock" sound very similar.
* "Go away" and "sock" - Again, no direct homophone, but they sound similar.
* "Buzz off" and "sock" - The closest homophone here might be "buss off", but that's not a common phrase.
It's a fun word puzzle! Let me know if you have another word in mind for the first part, and I can try to find a homophone!
