Sailor with waterproof coat found on road (6)
I believe the answer is:
tarmac
'coat found on road' is the definition.
'tarmac' can be an answer for 'coat' (tarmacing is a kind of coating). I am unsure of the 'found on road' bit.
'sailor with waterproof' is the wordplay.
'sailor' becomes 'tar' (slang term for a sailor).
'with' means one lot of letters go next to another.
'waterproof' becomes 'mac' (mac is a kind of waterproof).
'tar'+'mac'='TARMAC'
Can you help me to learn more?
(Other definitions for tarmac that I've seen before include "Airport runway surface" , "Airport runway(s)" , "Road-surfacing material" , "Road paving material" , "something for the road" .)
