Unknown character reflecting low buzzing sound (4)
I believe the answer is:
zoom
'buzzing sound' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'unknown character reflecting low' is the wordplay.
'unknown character' becomes 'z' (I am not sure about the 'unknown' bit.**).
'reflecting' shows that the letters should be reversed in order.
'low' becomes 'moo' ('moo' can be a synonym of 'low').
'moo' reversed gives 'oom'.
'z'+'oom'='ZOOM'
Can you help me to learn more?
(Other definitions for zoom that I've seen before include "Quickly shift" , "Belt along" , "Enlarge" , "Speed along - type of lens" , "Move swiftly with a buzzing sound" .)
