✕Common Mistakes
Les sont géniaux, d'autres sont ennuyeux.
"Les" would refer to a specific set already mentioned; "certains" is needed for an indefinite subset.
d' autre sont ennuyeux.
The apostrophe must be attached to "d'" and the word "autres" stays plural.
Certains sont génial, d'autres sont ennuyeux.
The adjective must agree with the plural subject: "génial" → "géniaux".
d'autres sont ennuyeuse.
Because the subject is masculine plural, the adjective must be "ennuyeux", not the feminine singular "ennuyeuse".

Cultural Tip
In French, "génial" is a casual, enthusiastic word often used for people, ideas, or experiences that impress you. "Ennuyeux" can sound a bit harsh, so in polite conversation you might soften it with "un peu ennuyeux" or choose a milder synonym like "pas très intéressant". Also, remember that the plural form of "génial" becomes "géniaux" (‑aux) while "ennuyeux" stays "‑eux".
