Morphology

tungstic + acid

The adjective 'tungstic' means 'of or relating to tungsten' and 'acid' denotes a chemical substance; combined they directly yield 'an acid of tungsten.' Although the term is specialized and low-frequency, the compositional chemical naming pattern (metal + -ic + acid) is regular and cross-linguistically transparent, so a learner who knows the constituents can infer the meaning.

Etymology

Tungstic acid gets its name from the metal tungsten, whose name comes from old Swedish words meaning 'heavy stone' because the metal came from very heavy rocks. The word acid shows it is an acid made from that metal, so tungstic acid means 'an acid of tungsten'.
