The kanji 装 combines the 衣 (clothing) radical with 壮, which implies strength or vitality. Together, it originally meant dressing in a formal or powerful way.

Today it extends to mechanical setups (like 装置) or artificial appearances — such as disguises or emotional facades (よそおう).

彼かれは 冷静れいせいを 装よそおっていた。
He pretended to be calm.

この装置そうちは 自動的じどうてきに 作動さどうします。
This device operates automatically.

“よそおう” is often used for appearances — either dressing up or putting on a facade.
“そう” appears in compound words like 装置 (apparatus) and 装飾 (ornament).
