Drunk robs Eve of watch (7)
I believe the answer is:
observe
'watch' is the definition.
(I know that watch can be written as observe)
'drunk robs eve' is the wordplay.
'drunk' indicates an anagram.
'robs'+'eve'='robseve'
'robseve' with letters rearranged gives 'OBSERVE'.
'of' is the link.
(Other definitions for observe that I've seen before include "Notice or make a remark" , "Witness, watch" , "Watch without intervening" , "See - say" , "Watch attentively" .)
