Deserve attention on a certain point (4)
I believe the answer is:
earn
'deserve' is the definition.
(I've seen this before)
'attention on a certain point' is the wordplay.
'attention' becomes 'ear' (have the ear of someone is to have their attention).
'on' is a charade indicator (letters next to each other).
'a certain point' becomes 'n' (N is an example. I am not sure about the 'certain' bit.).
'ear'+'n'='EARN'
Can you help me to learn more?
(Other definitions for earn that I've seen before include "Receive in return for" , "Win" , "Make; deserve" , "Warrant" , "Get (money) for work or labour" .)
