Tip of a plant? (5)
I believe the answer is:
shoot
'a plant?' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe there's an association between them I don't understand?
'tip of' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'shot' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for shoot that I've seen before include "Kill; part of plant" , "modelling session" , "Pump full of lead" , "Make a film" , "Use a gun; film" .)
