Sailor causing me total confusion (7)
I believe the answer is:
matelot
'sailor' is the definition.
(I've seen this before)
'me total confusion' is the wordplay.
'confusion' is an anagram indicator.
'me'+'total'='metotal'
'metotal' is an anagram of 'MATELOT'.
'causing' is the link.
(Other definitions for matelot that I've seen before include "A lot met (anag) - sailor" , "One at sea" , "Sailor (slang from French)" , "Rating" , "seafarer" .)
