What does Vous êtes très intelligent Je suis impressionnée que vous savez Françaises mean in french?

You are very smart I am impressed that you know French

I have to precise here.

Actually, the original sentence is not correct.

- It is either :

Vous êtes très intelligentes, je suis impressionée que vous sachiez, françaises.

translated

You are very smart, I am impressed that you know, you French (ladies)

Intelligentes is plural feminine because you adress to ladies.

Note : sachiez is the present conditionnal first form of the verb "savoir", often used after que ..

- or

Vous êtes très intelligent, je suis impressionée que vous connaissiez le français.

You are very smart I am impressed that you know French

(connaître is the accurate verb in this context) and you adress to a male.

To be more precise : the adjectives are not capitalized in french, on the contrary to english in which adjectives and common nouns related to countries are capitalized.

The French (people) - les français.

Hope this will help
