One who manages without current reproducing device (6)
I believe the answer is:
copier
'one who manages without current reproducing device' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'one who manages without current' is the wordplay.
'one who manages' becomes 'coper' (I've seen this in another clue).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'current' becomes 'I' (symbol for electric current).
'coper' going around 'i' is 'COPIER'.
Can you help me to learn more?
(Other definitions for copier that I've seen before include "Office item" , "Reproducer" , "Machine for making duplicates" , "unoriginal type" , "piece of office equipment" .)
