Whip near Keir regularly is party manager (7)
I believe the answer is:
caterer
'party manager' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'whip near keir regularly' is the wordplay.
'whip' becomes 'cat' (cat o' nine tails, cat for short is a type of whip).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'near'+'keir'='nearkeir'
The alternate letters of 'nearkeir' are 'erer'.
'cat'+'erer'='CATERER'
'is' is the link.
Can you help me to learn more?
(Other definitions for caterer that I've seen before include "One providing food and drink" , "Provision supplier" , "Provider of food and drink" , "One providing food and service for a party" , "Person who supplies food for social events" .)
