One way to hold countenance: not a face as a shape, but a face as something a person holds. You hold your face steady, or you let it fall; you turn it towards someone, or you turn it away. Read it that way and the meanings line up. The face itself, with the feeling showing on it. The face turned kindly towards someone — which is what open support looks like from the outside. And then the verb: to countenance something is to turn your face towards it and let it be seen there, with your name attached.
From the word’s history
From Middle English contenaunce, via Anglo-Norman and Old French contenance from contenir, and Late Latin continentia — a doublet of continence. The oldest idea is how a person holds or contains themselves: bearing, conduct, demeanour. English later narrowed it to the face.
來自中古英文 contenaunce，經由盎格魯-諾曼語和古法文 contenance（出自 contenir），背後是晚期拉丁文 continentia，和英文 continence 是同源雙生字。最早的意思是一個人「怎麼持住自己」——舉止、儀態。英文後來才把它收窄到臉上。
