Chase around pines (5)
I believe the answer is:
aches
'pines' is the definition.
('ache' can be a synonym of 'pine')
'chase around' is the wordplay.
'around' indicates an anagram.
'chase' anagrammed gives 'ACHES'.
(Other definitions for aches that I've seen before include "Hurts; yearns" , "Pains, hurts" , "sign of suffering" , "Constant pains" , "Continuous pains" .)
