What is a hinky pinky for copper teapot?

"Hinky pinky" is not a recognized term for a part of a copper teapot. It's likely a misunderstanding or a playful, informal name that's not widely used.

It's possible that someone was referring to one of these teapot parts:

* Spout: The part where the water pours out.

* Handle: The part you hold to lift the teapot.

* Lid: The cover that seals the teapot.

* Body: The main part of the teapot where the water is held.
