Morphology

stearate = stearic (opaque) = stear + ate

Formation follows chemical nomenclature (root 'stear-' + '-ate') and depends on technical knowledge of stearic acid, so it is not guessable to a general learner.

Etymology

Stearate comes from the Greek root stear meaning 'tallow' or 'fat' and the chemical ending -ate, as in carbonate. So stearate is basically a 'fat' turned into a salt or similar chemical, which is why it is used in soaps, cosmetics, and tablets.
