About
The character "牾" is structured as a phono-semantic compound with the semantic component "牛" (ox) and the phonetic component "吾" (wú), indicating an original sense of physical opposition akin to oxen butting heads. Over time, its meaning broadened from denoting such concrete confrontations to representing abstract contradiction or discord, with its usage now largely confined to compounds like "抵牾" which convey clashing ideas or inconsistencies.
