Put up with being restless? (5)
I believe the answer is:
stood
'put up with' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stood that I've seen before include "Tolerated; stayed upright" , "Rose to one's feet" , "Was a candidate for election" , "Was upstanding" , "Remained valid" .)
