Temporarily quiet or inactive (7)
I believe the answer is:
dormant
I believe this is a double definition.
'temporarily quiet' is the first definition.
(I've seen this before)
'inactive' is the second definition.
(I know that inactive can be written as dormant)
(Other definitions for dormant that I've seen before include "Inactive, but not dead" , "Latent" , "Temporarily inactive, being mordant" , "Inert" , "Sluggish" .)
