"He is a singer."
Translation:Il est chanteur.
In the hints they give examples "This is a dancer. C’est une danseuse. She’s a dancer. Elle est danseuse." If they are going to state this in the hints why then are the lessons disregarding the hint and saying "He is a singer" can be C'est un chanteur. Either the hint is wrong, or the it does not really matter and both are correct. I find this confusing and frustrating.
Unfortunately, the tiny module where hints are added is not very sophisticated, so links cannot be added there.
When I hover on "he is a", I can read "c'est un", which is just what you need for a translation.
Then, if you don't understand why "he is a" can translate to "c'est un", the sentence discussion here gives you the information you need.
