Short of ammunition? (4)
I believe the answer is:
ammo
This clue might be a double definition.
'short' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'ammunition' is the second definition.
(synonyms)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ammo that I've seen before include "explosives, perhaps" , "What's fired from a gun (abbr)" , "Bullets (sl.)" , "Bullets, say, in short" , "eg Bullets, shells" .)
