Morphology

phosphotungstic = tungstic + tungstic (semi-transparent) = phospho + tungst + ic

The structure 'phospho-' + 'tungstic' clearly indicates presence of phosphorus and tungsten in chemical nomenclature, but the combining forms are specialized and may be unfamiliar to general learners.

Etymology

The word phosphotungstic joins phospho- from phosphorus, which relates to 'light' as in the word phosphorescent, and tungst- from tungsten, whose name means 'heavy stone'. So, phosphotungstic describes a compound that has both a phosphorus part and a tungsten part.
