Morphology

trioxide = oxide (transparent) = tri + oxide

The word is directly formed by the numeric prefix 'tri-' (three) added to the chemical noun 'oxide', yielding a compound meaning 'an oxide with three oxygen atoms'.

Etymology

Trioxide breaks into tri- meaning 'three', like in triangle, and oxide meaning 'joined to oxygen', like in oxidize. So, a trioxide is a compound that has three oxygen atoms.
