Being in Kent city, initially ignored (6)
I believe the answer is:
entity
'being in' is the definition.
'entity' can be an answer for 'being' (I've seen this before). I am not certain of the 'in' bit.
'kent city initially ignored' is the wordplay.
'kent' becomes 'ent' (I am not sure about this - if you are sure you should believe this answer much more).
'initially ignored' means to remove the first letter.
'city' with its initial letter taken off is 'ity'.
'ent'+'ity'='ENTITY'
Can you help me to learn more?
(Other definitions for entity that I've seen before include "Presence" , "It exists as a seperate thing (6)" , "It exists as a separate thing" , "Essence, existence" , "Anything that exists" .)
