Questions & Answers about Elles sont très timides.
Why does timides have an 's' at the end?
Elles is feminine plural. Why didn't we add an extra 'e' to make timides feminine?
You are right that we usually add an 'e' to adjectives to make them feminine. However, the default masculine singular word for shy is timide, which already ends in an 'e'. When a masculine adjective already ends in an 'e', it stays exactly the same for the feminine form. Since the subject is plural, we just add the 's'.
Do I pronounce the 's' at the end of timides?
No, the 's' at the end of regular plural adjectives is silent. You pronounce the plural timides exactly the same way as the singular timide.
Since the 's' on Elles is silent, how can I tell if someone is saying 'She is' or 'They are' when listening?
