I’ll take the win, but I’m not sure how “chattering sounds” fits in🤔
Off RAPPORT:
Wear foot brace, or tea goes from hot to icy.(8)
“Chattering” is doubly used, as a signal it’s a soundailke, and as part of “chattering sounds” to define “rap.” So, sounds like RAP + OR to get RAPPORT. Not strictly kosher, but I couldn’t resist. 
Understood. Thanks!
Okay, back to the game.

I’m thinking it’s a sound alike and I’m trying to work off APERITIFS or APERITIVOS or APERITIVES as in A PAIR OF… but that’s where it falls apart.
ORTHOTIC doesn’t even have an “A” in it. How’s the answer gonna overlap with an “A?”
Here’s a hint, though: the word “each” has a fairly well-known abbreviation.
Oh yeah, overlap.

Well done. Go.
