Why do people say individuals instead of people?

Individuals is a 4- or 5-syllable word that sounds, in these contexts, like an item from the technical register of English; it sounds serious, elevated. People, in contrast, is a 2-syllable word from everyday speech — not slangy, or even particularly informal, but just an all-purpose ordinary plural. Feb 13, 2019
