Noun
がいめん
そとづら
ビエトは外面はいい人そうですが、実はとてもおそろしい一面を持っています。
On the surface, Viet looks like a nice guy, but he actually has a scary side.
外面だけがいい男性とけっこんし、外面は立ぱだけど内面はボロボロの中古住たくを買ってしまい、今とても苦労しているんです。
I'm married to a man who is an angel outside and a devil at home, and we bought an older home that has a fine exterior, but the interior is worn out, so I'm having a tough time right now.
彼の外面に騙されない方がいいですよ。私がインストラクターのことが嫌いだったのは、上司にはいい顔をして陰で後輩のことを小突き回していたからです。
You shouldn’t be fooled by his outward appearance. I hated my instructor because he showed his superiors a nice face while he bullied subordinates, including me, behind their backs.
The outside face to something is the exterior of that thing.
This is a jukugo word, which usually means on'yomi readings from the kanji. This reading is usually for building exteriors and outside surfaces. The other reading そとづら is used when a person's personality comes to the surface and is a bit of an exception, so you'll probably see it less often. Just keep those differences in mind!
