Lady wanting boy makes wishes (6)
I believe the answer is:
yearns
'wishes' is the definition.
(to yearn for something is to wish for it)
'lady wanting boy makes' is the wordplay.
I cannot really see how this works, but
'makes' could be 'earns' (as in making money) and 'earns' is found in the answer.
A single letter 'y' remains 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 yearns that I've seen before include "'Hankers, longs (6)'" , "'Craves, longs for (6)'" , "Longs for, pines" , "Craves, longs intensely" , "Desires strongly" .)
