Frequently used in formal writing, news, and academic prose where 'notice' would feel too casual. Only sense that takes a bare-infinitive complement (we observed him leave, not 'we observed him to leave' in modern usage).

常見錯誤

❌I observed him to leave the building.
✅I observed him leave the building.
💡after 'observe + object', use the bare infinitive, not 'to'.

常見錯誤

❌She observed silently that the door was open.
✅She noticed silently that the door was open.
💡if nothing is spoken, use 'notice', not 'observe' (in this remark sense).

✅You should follow your father's advice.
💡'observe' takes rules and customs, not personal advice.
