Run yet remain still (5)
I believe the answer is:
stand
This could be a double definition.
'run' is the first definition.
(thesaurus)
'remain still' is the second definition.
'stand' can be an answer for 'remain' (standing is a kind of remaining). I'm not certain of the 'still' bit.
'yet' acts as a link.
Can you help me to learn more?
(Other definitions for stand that I've seen before include "Support" , "stay the same in position" , "Sit here at a sports event" , "principled position" , "stick" .)
