Endurance to pick-up beastly type briefly for Eliot (7)
I believe the answer is:
stamina
'endurance' is the definition.
(stamina is a kind of endurance)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stamina that I've seen before include "Staying-power, endurance" , "grit" , "legs" , "Vigour" , "Energy and staying power" .)
