The very first thing that came to mind is a song by Credence Clearwater Revival - I Put a Spell On You.
Next, is as Alancaster149 offered with a familiar saying of me when working, which is "Let's rest a spell".
And, then in thought order is its use with grammar such as "How do you spell that?" I usually offer a humorous retort, although makes no sense, "with salt and pepper". Why? I simply dun'no . . .
