Up and about in Sarawak eventually (5)
I believe the answer is:
awake
'up and about' is the definition.
(I've seen this in another clue)
'in sarawak eventually' is the wordplay.
'in' says the answer is hidden in the clue.
'AWAKE' can be found hidden inside 'sarawak eventually'.
(Other definitions for awake that I've seen before include "Unable to sleep" , "Alive and alert" , "Conscious and (usually) open-eyed" , "On the ball?" , "Rouse; vigilant" .)
