Prohibition scuppered boat taking last of stingo (5)
I believe the answer is:
taboo
'prohibition' is the definition.
(I've seen this before)
'scuppered boat taking last of stingo' is the wordplay.
'scuppered' indicates an anagram ('scuppered' can mean damaged).
'taking' means one lot of letters goes inside another.
'last of' suggests the final letters.
The final letter of 'stingo' is 'o'.
'boat' is an anagram of 'tabo'.
'tabo' placed around 'o' is 'TABOO'.
(Other definitions for taboo that I've seen before include "Prohibited; ban" , "Forbidden for social reasons" , "Not permitted" , "ruled out" , "Prohibited as unclean or holy" .)
