杞悇

These characters combined do not form a regular word; however, individually, they convey distinct meanings. 'Qi2' (杞) usually refers to a small state during ancient China, symbolizing worrying unnecessarily about things beyond one's control; 'Sou1' (悇), although not frequently used, generally expresses worry or sorrow, similar to grief. Combined together, the user might intend to express over-anxiety about insignificant issues in life.
