One of the most typical mistakes that English learners commit is using the verb to be when they agree or disagree:
I am agree / I am not agree
It’s true that many Romance languages such as Catalan (estic d’acord), Spanish (estoy de acuerdo) or French (Je suis d’accord) use a linking verb in this expression, but not in English. In English “agree” is a verb, so we say:
I agree / I don’t agree
