About
牾 is a phono-semantic compound with the semantic radical 牛 (cow/ox) and phonetic component 吾. Its original meaning refers to the aggressive behavior of oxen, specifically the act of butting heads or clashing. This concrete image of confrontation later extended to the general sense of opposing or contradicting. Today, it appears mainly in compounds like 抵牾 (dǐwǔ), meaning a logical inconsistency or a conflict between statements or accounts.
