Approves another helping (7)
I believe the answer is:
seconds
This might be a double definition.
'approves' is the first definition.
Although both the answer and definition are verbs in their -s form, I don't see how they can define each other.
'another helping' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for seconds that I've seen before include "Short periods of time for supporters" , "Endorses proposal" , "Boxer's aides" , "More food!" , "Gives support to" .)
