The word 违反 is formed through the combination of two characters, 违 and 反, which each contribute a related meaning to create a new, unified concept. 违 (wéi) carries the core idea of "disobeying" or "going against", while 反 (fǎn) means "to oppose" or "to turn against". When joined, they do not simply list two actions but merge into a single, reinforced concept meaning "to violate" or "to contravene", where the sense of opposition from both characters intensifies the notion of breaking a rule or principle.
