Told to write 'meadow' the correct way (7)
I believe the answer is:
rightly
'told to write meadow' is the definition.
I can't tell whether this definition defines the answer.
'correct way' is the wordplay.
'correct' becomes 'right' (right can mean correct).
'way' becomes 'ly' (I can't justify this - if you can you should give a lot more credence to this answer).
'right'+'ly'='RIGHTLY'
'the' is the link.
Can you help me to learn more?
(Other definitions for rightly that I've seen before include "Justly, honestly" , "With good reason" , "Honestly or justifiedly" , "Justly, correctly" .)
