| Usage notes | Used in discussions to propose a hypothetical situation. It's suitable for formal and informal contexts. | Use 'presume' when you're making a reasonable guess based on available information. Avoid in formal situations that require certainty. Suitable for casual conversations. | Typically used in situations where you're making assumptions or predictions. It's less appropriate in formal writing. In casual talks, it can indicate uncertainty. |
