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 am not certain of the 'in' bit.
'lose oar tossed' is the wordplay.
'tossed' indicates anagramming the letters.
'lose'+'oar'='loseoar'
'loseoar' is an anagram of 'AEROSOL'.
'about' is the 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" .)
