The word **单人** (dān rén) is formed through the standard Chinese compounding process where two independent characters, each with their own meaning, combine to create a new, specific concept. The first character **单** (dān) means "single," "alone," or "solitary," functioning as a modifier. The second character **人** (rén) means "person" or "human," serving as the core noun. When combined, they create a noun phrase meaning "single person," commonly used as an adjective to describe things designed for one individual, such as a single bed (**单人床**) or a single room. This follows the prevalent "modifier + head noun" grammatical structure in Mandarin.
