The Chinese word "爱人" is formed by combining two individual characters: "爱", which means "love", and "人", which means "person". This compound word is created through a direct semantic fusion where "爱" modifies "人" to convey the concept of "a person who is loved", ultimately referring to a spouse or romantic partner. This formation reflects a common pattern in Chinese where meaningful characters are juxtaposed to express new, related ideas without altering the characters themselves, resulting in a term that intuitively captures the relationship through its constituent parts.
