Did judge set date and time for son to visit? (9)
I believe the answer is:
estimated
'did judge' is the definition.
(estimating is a kind of judging)
'set date and time for son to visit?' is the wordplay.
I cannot really see how this works, but
an anagram of 'set' is 'est' which is within the answer.
an anagram of 'date' is 'ated' which is present in the answer.
The remaining letters 'im' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for estimated that I've seen before include "Worked out" , "Approximated, reckoned" , "Calculated approximately" , "Rough" , "Guessed" .)
