The word 丧失 is formed by combining two characters, each contributing related meaning to create a unified concept. The first character, 丧 (sàng), carries the core idea of loss, particularly associated with death or mourning, implying something vital is gone. The second character, 失 (shī), means to lose, miss, or fail to keep. When placed together, they semantically reinforce and intensify each other, merging to express a profound, often complete, loss or forfeiture of something (like ability, reason, or territory), where the result is an absence or deprivation.
