Wrote off breakdown van? (5)
I believe the answer is:
tower
'breakdown van?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'wrote off' is the wordplay.
'off' indicates anagramming the letters.
'wrote' is an anagram of 'TOWER'.
Can you help me to learn more?
(Other definitions for tower that I've seen before include "One to pull" , "Stand very high (over)" , "Campanile, spire etc" , "See 6 Down" , "Steeple" .)
