Wanted to address politely indeed (7)
I believe the answer is:
desired
'wanted' is the definition.
(similar in meaning)
'address politely indeed' is the wordplay.
I cannot quite see how this works, but
'address' could be 'sire' (I have seen 'old address' mean 'sire' so perhaps 'address' could also mean 'sire') and 'sire' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for desired that I've seen before include "Had aspired to" , "Wanted strongly" , "Sought after" , "Craved" , "Lusted-after" .)
