Principal boy receives new bill (8)
I believe the answer is:
headland
'bill' is the definition.
(I've seen this before)
'principal boy' is the wordplay.
'principal' becomes 'head' (synonyms).
'boy' becomes 'land' ().
'head'+'land'='HEADLAND'
'receives new' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for headland that I've seen before include "Bill" , "Promontory, area jutting out into the sea" , "Narrow promontory" , "Ness" , "Cape" .)
