Man overseas resigned over Omicron disease spreader (8)
I believe the answer is:
mosquito
'omicron disease spreader' is the definition.
I can't tell whether this defines the answer.
'man overseas resigned over' is the wordplay.
'man overseas' becomes 'mos' (I can't explain this - if you can you should believe this answer much more).
'resigned' becomes 'quit' (I've seen this in another clue).
'over' becomes 'o' (cricket abbreviation).
'mos'+'quit'+'o'='MOSQUITO'
Can you help me to learn more?
(Other definitions for mosquito that I've seen before include "Disease-bearing fly" , "Malaria-carrying insect" , "Insect - WWII fighter-bomber" , "Plane used in WWII" , "Kind of blood-sucking tropical gnat" .)
