Not so much snooty as inquisitive (4)
I believe the answer is:
nosy
'inquisitive' is the definition.
(nosy means overly inquisitive or curious)
'not so much snooty' is the wordplay.
'not' becomes 'no' (I've seen this in other clues).
'much' means to remove the last letter (much but not all of the word).
'snooty' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
'so' with its final letter taken off is 's'.
'no'+'s'+'y'='NOSY'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for nosy that I've seen before include "Fragrant" , "Meddlesome" , "Over-inquisitive" , "lots of questions" , "Showing too much curiosity about people's affairs" .)
