Flash cards displaying different definitions (french)
I was taught that nuit is night and est is is, but the flash cards have nuit as 'harmful' and est is 'east'.
You ran into two French words that have multiple meanings. "Est" can also mean "east, and "nuit" is also the third person singular conjugation for the verb "nuire à", which means "to harm" or "to be detrimental to".
In any case, this doesn't mean that everything in the flashcards is correct. Several others have found mistakes. Unfortunately, there is no current way (that I know of) to report mistakes in the flashcards.
