Teams write off a passing criticism (9)
I believe the answer is:
sideswipe
'a passing criticism' is the definition.
'sideswipe' can be an answer for 'criticism' (I've seen this before). I'm not sure about the 'a passing' bit.
'teams write' is the wordplay.
'teams' becomes 'sides' (eg football sides).
'write' becomes 'wipe' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sides'+'wipe'='SIDESWIPE'
'off' is the link.
Can you help me to learn more?
(Other definitions for sideswipe that I've seen before include "Criticism" , "Glancing blow" , "Passing critical remark" , "indirect strike action" , "jibe when passing" .)
