A host with a bit of money as a neighbour (8)
I believe the answer is:
adjacent
'as a neighbour' is the definition.
I can't tell whether this defines the answer.
'a host with a bit of money' is the wordplay.
'a host with' becomes 'adj' (I can't justify this - if you can you should give a lot more credence to this answer).
'bit of money' becomes 'cent'.
'adj'+'a'+'cent'='ADJACENT'
Can you help me to learn more?
(Other definitions for adjacent that I've seen before include "Nearby" , "Adjoining, lying near" , "Next-door" , "Alongside" , "next door" .)
