Anxiety, when taking off top to show boob (5)
I believe the answer is:
error
'boob' is the definition.
(I've seen this before)
'anxiety when taking off top to' is the wordplay.
'anxiety when' becomes 'err' (I can't justify this - if you can you should believe this answer much more).
'taking off top' means to remove the first letter.
'to' becomes 'for'.
'for' with its first letter taken away is 'or'.
'err'+'or'='ERROR'
'show' is the link.
Can you help me to learn more?
(Other definitions for error that I've seen before include "Faulty judgment" , "1 down" , "Mistake, lapse" , "Howler" , "heresy" .)
