Passionate after river drive, perhaps (3,4)
I believe the answer is:
tee shot
'drive perhaps' is the definition.
'tee shot' can be an answer for 'drive' (I've seen this before). I'm unsure of the 'perhaps' bit.
'passionate after river' is the wordplay.
'passionate' becomes 'hot' (associated in meaning).
'after' says to put letters next to each other.
'river' becomes 'tees' (River Tees ).
'hot' put after 'tees' is 'TEE-SHOT'.
Can you help me to learn more?
(Other definitions for tee shot that I've seen before include "Drive" , "First stroke towards hole in golf" .)
