Not fully a sailor, being bowled over in restrictive situation (7)
I believe the answer is:
rattrap
'restrictive situation' is the definition.
'rattrap' can be an answer for 'situation' (I have seen 'Difficult situation ' mean 'rattrap' so perhaps 'situation' could also mean 'rattrap'). I am not sure about the 'restrictive' bit.
'not fully a sailor being bowled over' is the wordplay.
'not fully' becomes 'part' (I can't justify this - if you can you should believe this answer much more).
'a sailor' becomes 'tar' (slang term for a sailor).
'being bowled over' says the letters should be written backwards.
'part'+'tar'='parttar'
'parttar' reversed gives 'RATTRAP'.
'in' is the link.
Can you help me to learn more?
(Other definitions for rattrap that I've seen before include "Agreeable; Mediterranean resort" , "Rodent catcher - found on a bicycle!" , "Rodent snare" , "Means of catching rodent" , "Difficult situation" .)
