Right paddle makes sound possibly heard in the forest (4)
I believe the answer is:
roar
'sound possibly heard in the forest' is the definition.
I can't judge whether this defines the answer.
'right paddle' is the wordplay.
'right' becomes 'R' (common abbreviation).
'paddle' becomes 'oar' (I've seen this before).
'r'+'oar'='ROAR'
'makes' is the link.
Can you help me to learn more?
(Other definitions for roar that I've seen before include "24 [BOOM]" , "Deep-throated cry" , "engine noise" , "Zoom - prolonged cry" , "Bawl, bellow" .)
