Read the notes (7)
I believe the answer is:
intoned
'read' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally define each other.
'the notes' is the wordplay.
I cannot really see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'notes' could be 'ed' and 'ed' is found within the answer.
The remaining letters 'inon' 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 intoned that I've seen before include "Recited in chanting voice" , "Started a psalm, perhaps" , "Sang in church" , "sounded like the vicar?" , "Said flatly" .)
