Charm half of them with report (4)
I believe the answer is:
item
'report' is the definition.
(I've seen this before)
'charm half of them' is the wordplay.
'charm' becomes 'it' (intangible human quality: 'she has it').
'half of' means to take half the letters.
'them' with half the letters taken is 'em'.
'it'+'em'='ITEM'
'with' is the link.
(Other definitions for item that I've seen before include "One thing among many" , "Individual unit in a list" , "Single thing, poor mite" , "Detail (in a list)" , "Individual article or unit" .)
