Queen perhaps with two words of hesitation for provider of food (7)
I believe the answer is:
caterer
'provider of food' is the definition.
(I've seen this before)
'queen perhaps with two words of hesitation for' is the wordplay.
'queen perhaps' becomes 'cat' (a female cat is a queen).
'with' means one lot of letters go next to another.
'two' shows that letters should be duplicated.
'words of hesitation for' becomes 'er' (I can't justify this - if you can you should believe this answer much more).
'er' doubled is 'erer'.
'cat'+'erer'='CATERER'
Can you help me to learn more?
(Other definitions for caterer that I've seen before include "Provider of food/drink" , "Person who supplies food for social events" , "One providing food and service for a party" , "Provision supplier" , "Provider of refreshments" .)
