IPA: /ˈɒksɪdaɪzəbl/
KK: /ˈɑksɪdaɪzəbl/
Able to undergo a chemical reaction where a substance combines with oxygen or loses electrons.
Iron is oxidizable, which is why it rusts when exposed to moisture and air.
Oxidizable → It is formed from "oxid" (from Latin "oxydare", meaning to combine with oxygen) and "-izable" (meaning capable of). The word "oxidizable" refers to a substance that is capable of undergoing oxidation or combining with oxygen.
Think of a substance that can 'combine with oxygen' ('oxid') — that's why 'oxidizable' means it can undergo oxidation.
