Suggestion for a possible clarification
I have a 'suggestion' regarding the last 3 words of the sentence << "Some nouns, like l'élève ("the student"), have the same spelling and meaning in both forms." >.
Where I found that sentence: It was (and it probably still is) the first sentence of the second paragraph under the [sub-section?] heading "Noun Genders", under the (section) heading "Tips and notes", at [the URL] https://www.duolingo.com/skill/fr/Animals .
At first, I was confused. I did not understand that (and I did not know whether) the phrase "in both forms" meant "both in the masculine form and in the feminine form". (Does it?)
If so, then I would suggest to change "in both forms" to something like "in both the masculine and the feminine forms".
Just a suggestion.
But the actual genders were not defined. "Both forms" was mentioned before defining what the French gender forms are: "masculine" and "feminine." For all they know, French could also have more than three genders like German.
We can add something simple in the beginning like "French has two grammatical genders: masculine and feminine." Then it would be plain.
