Casual worker using voice? About time (8)
I believe the answer is:
temporal
'about time' is the definition.
(I've seen this before)
'casual worker using voice?' is the wordplay.
'casual worker' becomes 'temp' (short-term or temporary worker).
'using voice?' becomes 'oral' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'temp'+'oral'='TEMPORAL'
Can you help me to learn more?
(Other definitions for temporal that I've seen before include "Of wordly affairs, not spiritual" , "Relating to time" , "profane" , "Limited by time" , "Worldly, secular" .)
