Refrains from being so avid, perhaps (6)
I believe the answer is:
avoids
'refrains from' is the definition.
('avoid' can be a synonym of 'refrain from')
'so avid perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'so'+'avid'='soavid'
'soavid' with letters rearranged gives 'AVOIDS'.
'being' is the link.
(Other definitions for avoids that I've seen before include "Escapes" , "Steers clear of, dodges" , "Ducks (out of)" , "Shuns, keeps away from" , "Keeps away or refrains from" .)
