From mouth, put out narrow tongue (4)
I believe the answer is:
spit
This clue is a double definition.
'from mouth put out' is the first definition.
(to spit from one's mouth)
'narrow tongue' is the second definition.
(tongue and spit can both mean a piece of land)
(Other definitions for spit that I've seen before include "Eject from mouth" , "Headland, saliva" , "Narrow peninsula" , "Thin metal spike to hold roasting meat" , "issue with some violence" .)
