? blond instead of blonde may be a more consistent American spelling of the term, but it is by no means universal, and is rarely spelt this way outside of the United States - exceptions include schools in other countries which offer an American curricula. Conversely brunette is far more common than brunet in most literary sources, both American and International - I picked up an American copy of Glamour just the other day and saw no less than 17 references to Brunette.
Keep calm and report. Your comments will not speed it up. But now you have cluttered the comment section, and after fixing the error you've been complaining about, this thread is going to stay up, and the new meaningful questions are going to be all the way down there.
I am sorry that the contributors have not been checking the reports for 3 years. We have better tools now.
We are only four. Some of us are new, like me, and have to clean up this mess.
Maybe it has reduced that way to common usage, but the proper usage is blond=male and blonde=female. Brunet is also proper for a man, but most people don't use it because it sounds feminine. The Ukrainian authors of this course are familiar with the proper English, as shown by this exercise.
While that is what I write myself, I would not say it is "proper." English has no language authority on the model of the Academie Francaise, nor even a state-sanctioned dictionary. One might adopt a particular style guide, but there is nothing that makes one more "proper" than another. This is particularly true if you are trying to make a statement about English as a whole, since it is spoken natively around the world in a bewildering variety of dialects.
Well at least blond and blonde sound identical. It's only a written difference. But it sounds wrong to refer to a man as a "brunette," the French word for "dark-haired female." The French "brunet" is pronounced differently. The "t" is silent. But in English I guess "brunette" and "brunet" would sound the same?
