She's got the right angle on fruit (5)
I believe the answer is:
pearl
'she's' is the definition.
'the right angle on fruit' is the wordplay.
'the right angle' becomes 'L' (the shape of the letter is a right angle).
'on' means one lot of letters go next to another.
'fruit' becomes 'pear' (pear is a kind of fruit).
'l' after 'pear' is 'PEARL'.
'got' is the link.
(Other definitions for pearl that I've seen before include "Much loved and valued person" , "Off-white colour" , "Gem from oyster" , "Lustrous globule prized as a gem" , "Oyster's gem" .)
