A US singer initially opted to go for a state of temporary inactivity (8)

I believe the answer is:
abeyance
'temporary inactivity' is the definition.
(I've seen this in another clue)
'a us singer initially opted to go for a state' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for abeyance that I've seen before include "Temporary pause - suspension" , "To be in ... is to be suspended for a time" , "Recess" , "Placed in . . . . . . . . - suspended for a while" , "(Of laws etc) the condition of not being used" .)
