One of my friends was handing out our geography tests. With a look of understanding pity, he hands another of my friends her test with a F scribbled on top. "Pas terrible," he says, which I translated as "not terrible". Wait, huh? No detectable sarcasm about a test that was fairly terrible...
Flash forward to my host mom telling me about a walk and discussion she'd had earlier that day. "It was terrible," she tells me, with a huge grin.
"Hang on.. what does terrible mean?"
"It's like... good."
Yes, in french, the word terrible means good.
I need to stop getting thrown off by little things like that in French. But all I can do is sigh, think to myself in a tone of amused (and somewhat bemused) wonder, "Oh, French." And roll my eyes.
