For nous, do you pluralize the adjective? For example "nous sommes bizarres?"
Yes, you do in practically all cases.
The exception is in formal usage when "nous" is used to stand for one single person. This usage is called the "nous de majesté ou de modesté".
Note:
Do not forget the gender, as in:
"Nous sommes étonnées..." for a group of females speaking.
Do not mix up “nous” and “vous”
Vous is used to address more than one person or to address one person formally
Thus , « vous êtes bizarres », or « vous êtes bizarre » are both possible
To determine whether to pluralize the adjective in French, such as "nous sommes bizarres" (we are weird), you need to consider the agreement based on the noun being described.
In this case, "nous" is the pronoun for "we," which is a plural subject. The adjective "bizarre" also needs to agree in number and gender with the subject. Since "nous" is plural and of mixed gender, you would use the plural form of the adjective, which is "bizarres" to match.
So, the correct sentence would be "Nous sommes bizarres," where "nous" (we) is plural, and "bizarres" (weird) is also plural to agree with the subject.
