Looks for way to sign off (7)
I believe the answer is:
regards
'looks' is the definition.
(regard is a kind of look)
'way to sign off' is the wordplay.
I cannot really see how this works, but
'way' could be 'rd' (short for road) and 'rd' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for regards that I've seen before include "Best wishes" , "a well-wisher's utterance" , "Gets a load of" , "Carefully considers" , "Observes" .)
