Say crew get into trouble (7)
I believe the answer is:
mention
'say' is the definition.
(I know that mention is a more specific form of the action say)
'crew get into trouble' is the wordplay.
'crew' becomes 'men' (I've seen this before).
'get' is an insertion indicator.
'trouble' indicates an anagram.
'into' anagrammed gives 'ntio'.
'men' placed around 'ntio' is 'MENTION'.
(Other definitions for mention that I've seen before include "Remark" , "Passing reference" , "Cite; quote" , "state" , "Briefly refer to (something)" .)
