Is out of town creating notions of perfection (6)
I believe the answer is:
ideals
'notions of perfection' is the definition.
(I've seen this in another clue)
'is out of town' is the wordplay.
'out' means to remove the last letter.
'of town' becomes 'deals' (I can't justify this - if you can you should believe this answer much more).
'is' with its last letter removed is 'i'.
'i'+'deals'='IDEALS'
'creating' is the link.
Can you help me to learn more?
(Other definitions for ideals that I've seen before include "Highest standards, model objectives" , "100%? > 10 out out of 10? > With capital, more would want these" , "High values for ladies" , "Noble aspirations for ladies" , "Standards of perfection" .)
