A way to stir oxygen involved in oxidation (5)
I believe the answer is:
roust
'a way to stir' is the definition.
I can't judge whether this defines the answer.
'oxygen involved in oxidation' is the wordplay.
'oxygen' becomes 'O' (atomic symbol for oxygen).
'involved in' indicates putting letters inside.
'oxidation' becomes 'rust' (rust is a kind of oxidation).
'o' going inside 'rust' is 'ROUST'.
Can you help me to learn more?
(Other definitions for roust that I've seen before include "Rouse, disturb" , "Wake up" , "Treat roughly - disturb" , "Get out of bed maybe" , "Create stir" .)
