River meals referred to in speech (4)
I believe the answer is:
tees
'river' is the definition.
(River Tees)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for tees that I've seen before include "banker" , "Starting places on the golf course" , "Golf ball props" , "Sides of Trent" , "River in NE England" .)
