The Chinese word 低落 is a compound formed by combining two semantically related characters: 低 (dī), meaning "low" or "lowly", and 落 (luò), meaning "to fall" or "to decline". Together, they create a metaphorical and psychological meaning, where the concept of physically falling or being low is applied to mood or morale. The term thus denotes a state of being downcast, depressed, or in low spirits, effectively visualizing an emotional or motivational "decline" as a literal descent.
