Power to begrudge here (7)
I believe the answer is:
present
'here' is the definition.
(similar in meaning)
'power to begrudge' is the wordplay.
'power' becomes 'p'.
'to begrudge' becomes 'resent' (synonyms).
'p'+'resent'='PRESENT'
(Other definitions for present that I've seen before include "Hand over < donation" , "Reveal < a gift" , "Current" , "Give - what's received at Christmas?" , "gift > offer" .)
