Top ten single Queen's penned promoted stillness (7)
I believe the answer is:
inertia
'stillness' is the definition.
(I've seen this before)
'top ten single queen's penned promoted' is the wordplay.
I cannot really see how this works, but
'single' could be 'i' (one) and 'i' is found in the answer.
'queen' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for inertia that I've seen before include "Passiveness" , "Disposition to do nothing" , "Lack of activity" , "Disinclination to move" , "motionless?" .)
