| Usage notes | The verb 'be' is used in many contexts to describe states or conditions, and it can be used in different tenses (am, is, are, was, were). It's essential for forming sentences but might be omitted in casual speech. | Use 'happen' in everyday conversation. Avoid using it in very formal writing. It's appropriate for casual discussions but may sound too informal in academic contexts. | Use 'live' to talk about existence or actions happening in real-time. It's suitable for most contexts, both spoken and written. Avoid in overly formal texts where more precise verbs like 'reside' may be preferred. | Commonly used in formal and neutral contexts, such as scientific writing or news reports. Less common in casual conversations. |
