Choose from a selection (5)
I believe the answer is:
elect
'choose' is the definition.
(I know that elect is a more specific form of choose)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for elect that I've seen before include "Choose by voting" , "Exclusive group" , "Put into power through the ballot box" , "Vote to put into power" , "Make" .)
