I destroy museum close to Whitehall (6)
I believe the answer is:
vandal
'i destroy' is the definition.
I can't judge whether this definition defines the answer.
'museum close to whitehall' is the wordplay.
'museum' becomes 'V and A' (Victoria and Albert Museum).
'close to' indicates one should take the final letters (the close/ending of).
The last letter of 'whitehall' is 'l'.
'vanda'+'l'='VANDAL'
Can you help me to learn more?
(Other definitions for vandal that I've seen before include "Person who damages property maliciously" , "Hooligan" , "Cultural destroyer" , "Wanton destroyer" , "One who damages things maliciously" .)
