Investor leaves reservations to the listeners (4)
I believe the answer is:
ears
'listeners' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ears that I've seen before include "Listening organs" , "One's hearing aids" , "''He who has ... to hear, let him hear'' (bible)" , "Locations for buds or studs?" , "Spikes of corn" .)
