| Usage notes | Commonly used in both scientific and everyday contexts. Avoid using in very casual speech. | Commonly used in both spoken and written English. Appropriate in academic, professional, and casual contexts, but avoid in overly formal settings where synonyms like 'ascertain' may be preferred. | Use 'observe' when you are watching something closely or carefully. It is a neutral term suitable for both formal and informal contexts, but it may not be suitable for casual conversations where simpler words like 'watch' may work better. | Use 'recognize' when acknowledging something you already know. It's appropriate for everyday conversations but avoid in situations requiring formal language, like legal documents. | Use 'spot' when you want to indicate noticing something, often unexpectedly. It’s neutral and suitable for both casual conversations and more serious discussions. Avoid using it in very formal writing. |
