Clear empty can, one tin drunk (8)
I believe the answer is:
innocent
'clear' is the definition.
(similar in meaning)
'empty can one tin drunk' is the wordplay.
'empty' suggests removing the centre.
'drunk' is an anagram indicator.
'can' with its middle taken out is 'cn'.
'cn'+'one'+'tin'='cnonetin'
'cnonetin' with letters rearranged gives 'INNOCENT'.
(Other definitions for innocent that I've seen before include "Pope" , "Virgin" , "not intending to cause offence?" , "Naive or not guilty" , "Without blame or guilt" .)
