Decrease salary, with cut for a division of Human Resources (4,3)
I believe the answer is:
iron age
'division of human resources' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'decrease salary with cut for a' is the wordplay.
I cannot quite see how this works, but
'decrease' could be 'iron' (de-crease: remove creases by ironing) and 'iron' is located in the answer.
'a' is present in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for iron age that I've seen before include "It followed the Bronze Age" , "Period from about 1100 BC" , "Very old period" , "A region (anag) - period long ago" , "prehistoric times" .)
