Pet initially reared in the Potteries? (6)
I believe the answer is:
stroke
'pet' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stroke that I've seen before include "Mark made by brush" , "Drawn line; caress" , "one of rowing crew" , "Fondle - rower" , "Line made by pen" .)
