Narrow point of land (4)
I believe the answer is:
spit
'narrow point of land' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for spit that I've seen before include "Put on skewer" , "A spade's depth, in earth" , "Layer of earth" , "Meat may be roasted on it" , "Skewer -- exact likeness" .)
