Contemporary with part-timer (4)
I believe the answer is:
temp
'part-timer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'contemporary with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'TEMP' is hidden in the letters of 'contemporary'.
Can you help me to learn more?
(Other definitions for temp that I've seen before include "Short-term office worker" , "Transitory office worker" , "relief" , "N on-permanent worker" , "Non-full time employee" .)
