In everyday language one might speak of taandunud hind or taandunud koormus to indicate lower prices or reduced burden. In scientific and technical writing, taandunud is used to describe reduced states or species in processes such as reductions in chemistry (taandumine) or related measurements, for example taandunud kontsentratsioon or taandunud rõhk, though more common collocations can vary by field.
