Questions & Answers about Não que o nosso ambiente seja tóxico, mas estou insatisfeito.

Why does 'Não que' trigger the subjunctive verb 'seja' here?

The phrase Não que (Not that) is used to reject a potential assumption or a presupposed cause. Because you are explicitly denying that this scenario is the reality behind your feelings, Portuguese requires the subjunctive mood. seja is the present subjunctive of ser.

Why do we use a form of 'ser' for the environment being toxic, but 'estar' for being dissatisfied?

This sentence perfectly contrasts these two verbs! An environment being toxic is treated as an inherent characteristic or defining quality of the workplace, so we use ser (via seja). Conversely, feeling dissatisfied is a temporary emotional state or condition, so we use estar (via estou).

Why is there an 'o' before 'nosso'? Is it strictly necessary?

In European Portuguese, using the definite article before a possessive pronoun (like o nosso, a minha) is the standard, everyday rule. While it is sometimes dropped in very formal or literary writing, leaving the o out in everyday speech would sound unnatural in Portugal.

Would it ever be correct to use the imperfect subjunctive ('fosse') instead of 'seja' in this phrase?
