In popular government it's noted for its slowness (5)
I believe the answer is:
largo
'noted for its slowness' is the definition.
I can't tell whether this definition defines the answer.
'in popular government it's' is the wordplay.
'in' indicates a hidden word.
'LARGO' can be found hidden inside 'popular government ts'.
Can you help me to learn more?
(Other definitions for largo that I've seen before include "Played with dignified slowness" , "(Musically) slow in tempo and broad in manner" , "Slow passage" , "Mus. slow movement" , "To be played slowly and broadly" .)
