To make ‘be’ negative for ‘I,’ ‘you,’ and ‘we,’ you add not after the verb. This is a basic rule for A1 English. For ‘I,’ we say I am not or the short form I’m not. For ‘you’ (singular or plural) and ‘we,’ we use are not. In everyday conversation, are not often becomes the contracted form aren’t. These negative forms are essential for talking about things that are pas true or for correcting information. For example, I’m not from Spain, You aren’t a student here, et We aren’t ready. Mastering these forms helps you communicate clearly in English.
