Curve in larch (3)

I believe the answer is:

arc

'curve' is the definition.
(arc is a kind of curve)

'in larch' is the wordplay.
'in' says the answer is hidden in the clue.
'ARC' can be found hidden inside 'larch'.

(Other definitions for arc that I've seen before include "Curve of car" , "circle? Not entirely" , "Curvature" , "A curve for Joan of . . ." , "Curved path" .)

I've seen this clue in The Sun.
