| Usage notes | Use 'approximate' when you want to suggest an estimate rather than an exact number. It's suitable for academic and everyday contexts. Avoid using it in very casual conversations. | Use 'estimate' in formal and informal contexts when discussing predictions or calculations. Avoid in casual conversations unless talking about numbers. | Used when referring to physical or figurative closeness. Generally acceptable in both spoken and written contexts.
