Morphology

barium + dioxide

The term is directly compositional: 'barium' (the element) plus 'dioxide' (an oxide containing two oxygen atoms) yields a compound of barium with two oxygens, which a learner who knows both constituents can infer. Specific properties like its color, toxicity, or use as an oxidizing agent are domain-specific and not predictable from the words, but the basic chemical identity is transparent.

Etymology

Barium dioxide gets its name from the metal barium and the parts di- and oxide. Barium comes from a Greek word meaning 'heavy', and di- plus oxide literally say 'two' 'oxygen', so the name tells you it is a heavy element joined to two oxygen atoms, a clear image that helps you remember this oxygen-rich, toxic white powder.
