Waterproof coat found by a mother – something on road? (7)
I believe the answer is:
macadam
'something on road?' is the definition.
I can't tell whether this defines the answer.
'waterproof coat found by a mother' is the wordplay.
'waterproof coat' becomes 'mac' (I've seen this before).
'found by' says to put letters next to each other.
'mother' becomes 'dam' (female parent of an animal).
'mac'+'a'+'dam'='MACADAM'
Can you help me to learn more?
(Other definitions for macadam that I've seen before include "Paving material" , "(Inventor of) road surface" , "Tarmac" , "Road surfacing material" , "Road surface made of broken stone and tar" .)
