Royal figure not quite intent to have post redirected (7)
I believe the answer is:
william
'royal figure' is the definition.
The definition suggests a singular noun which matches the answer.
'not quite intent to have post redirected' is the wordplay.
I cannot quite see how this works, but
'intent' could be 'will' (will is a kind of intent) and 'will' is found in the answer.
The remaining letters 'iam' 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 william that I've seen before include "I am a weakish speller (anag) -- author" , "Prince Harry's brother" , "-- Caxton, early printer" , "Bill" , "Boy's name" .)
