Area with rather attractive grave (5)
I believe the answer is:
acute
'grave' is the definition.
(I've seen this before)
'area with rather attractive' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'with' means one lot of letters go next to another.
'rather attractive' becomes 'cute' (cute can mean attractive).
'a'+'cute'='ACUTE'
(Other definitions for acute that I've seen before include "Discerning" , "less than right" , "Keen; severe" , "Sharp; severe" , "Sharp - sort of French accent" .)
