What may help one drive and drink we hear (3)
I believe the answer is:
tee
'what may help one drive' is the definition.
I can't judge whether this definition defines the answer.
'drink we hear' is the wordplay.
'drink' becomes 'tea' (tea is a drink).
'we hear' indicates a 'sounds like' (homophone) clue.
'tea' is a homophone of 'TEE'.
'and' is the link.
Can you help me to learn more?
(Other definitions for tee that I've seen before include "Golfer's support" , "supporter on course" , "Mark" , "Starting place for a golfer" , "Golfing equipment" .)
