Drink close to park in wood (4)
I believe the answer is:
teak
'wood' is the definition.
(teak is a kind of wood)
'drink close to park' is the wordplay.
'drink' becomes 'tea' (tea is a kind of drink).
'close to' suggests the final letters (the close/ending of).
The final letter of 'park' is 'k'.
'tea'+'k'='TEAK'
'in' acts as a link.
(Other definitions for teak that I've seen before include "Take away with very hard wood" , "E. Indies hardwood" , "Type of wood" , "Quality timber" , "Hardwood tree" .)
