| Common mistakes | Using in overly formal contexts., Confusing with 'That's strange' - similar but 'weird' has a stronger connotation., Not using the contraction (That's) - sounds more natural to shorten. | Confused with 'unusual' vs 'usual'., Misuse in negative sentences, like saying 'not unusual' when you mean something is common., Using 'unusual' when 'unique' would be more appropriate. |
| Usage notes | Use when something feels odd or unexpected; appropriate in casual contexts but can seem unprofessional in formal settings. | Use 'unusual' to describe something that is different from what is typical. It's suitable for both spoken and written contexts, but may sound less natural in very informal conversations. |
