Narrows toward a point (6)
I believe the answer is:
tapers
'narrows toward a point' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tapers that I've seen before include "Makes or becomes gradually narrower" , "Prates about slender candles" , "Prates about candle lighters" , "Repast with slender candles" , "Narrows toward a point" .)
