Way men master rage (5)
I believe the answer is:
storm
'rage' is the definition.
('storm' can be a synonym of 'rage')
'way men master' is the wordplay.
'way' becomes 'st'.
'men' becomes 'or' (I've seen this in other clues).
'master' becomes 'm'.
'st'+'or'+'m'='STORM'
(Other definitions for storm that I've seen before include "Trouble" , "- drain; - cloud" , "Sandy, perhaps" , "Very unfavourable climate" , "Charge" .)
