Archer may fire or speak with it (5)
I believe the answer is:
twang
'archer may fire' is the definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'speak with it' is the wordplay.
'speak' becomes 'wang' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'wang' after 't' is 'TWANG'.
'or' is the link.
Can you help me to learn more?
(Other definitions for twang that I've seen before include "Plucked string sound; nasal voice" , "Nasal or musical sound" , "Pluck (a string)" , "Harsh sound of plucked string" , "Plucking sound - nasal tone" .)
