fine residence, shop, store
廛 centers on a place of trade or dwelling: a shop, store, or fine residence. The meanings share the idea of a commercial or upscale building.
廛 combines 广 (building) with an inner component that likely relates to a dwelling or marketplace. The exact historical development is uncertain.
The outer 广 is a building with a roof. Inside, picture a busy shop or an elegant residence: 廛 is a fine store or home.
For テン, imagine a shop with ten counters: ten -> テン, and each counter is part of the fine store.
