Professional input for a circle working and working both ways (10)
I believe the answer is:
reciprocal
'working both ways' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'professional input for a circle working' is the wordplay.
I cannot really understand how this works, but
'professional' could be 'pro' (abbreviation) and 'pro' is found in the answer.
'a' is found in the answer.
an anagram of 'circle' is 'recicl' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for reciprocal that I've seen before include "Done in return" , "Mutual" , "with give and take" , "Cross" .)
