Lose oar tossed about in spray (7)
I believe the answer is:
aerosol
'in spray' is the definition.
'aerosol' can be an answer for 'spray' (as in an aerosol spray). I'm not sure about the 'in' bit.
'lose oar tossed' is the wordplay.
'tossed' indicates an anagram.
'lose'+'oar'='loseoar'
'loseoar' anagrammed gives 'AEROSOL'.
'about' acts as a link.
Can you help me to learn more?
(Other definitions for aerosol that I've seen before include "Atomiser" , "Pressurized container" , "See 17 down [CONTAINER]: under pressure" , "Spray creator" , "Mister" .)
