Learn French: Ce ballet est de plus en plus complexe. - This ballet is more and more complex.

To say "more and more [adjective]" in French, you simply place the phrase de plus en plus directly before the adjective. It is completely invariable, meaning it never changes to match the gender or number of the noun. It will always be de plus en plus whether you are talking about a masculine, feminine, singular, or plural noun.

How do I pronounce the word plus in this specific sentence?

Pronouncing plus can be tricky! In the phrase de plus en plus, the first plus makes a mandatory liaison with en, so the 's' is pronounced like a "z". The second plus in this sentence is followed by a consonant (complexe), so its 's' remains completely silent. The whole phrase sounds roughly like "de ploo-zahn-ploo complexe".

Wait, ballet is masculine. Why does the adjective complexe end in an 'e'?

While it's true that adding an 'e' is the standard way to make a French adjective feminine, some adjectives just naturally end in an 'e' in their base, masculine form. Complexe is one of these words. Because it already ends in an 'e', its masculine and feminine forms are spelled exactly the same.

Why do we use ce for "this" ballet instead of cet?
