A where with a name — and the verb of setting a thing into its own.
Latin platea (a broad street, open space), from Greek πλατεῖα (plateia, broad way), from πλατύς (platys, broad, flat); a where with a name descends from the word for an open, level space.
A where with a name, and also the act of setting a thing into the where that belongs to it.
