Confusing 'rare' with 'rarely', which has a different meaning., Using 'rare' to describe frequency instead of quality., Misplacing 'rare' in sentences, leading to unclear meaning.
用法说明	Use 'occasional' to describe something that happens at irregular intervals. It is appropriate in both spoken and written contexts but is more common in written language than casual conversation.	Used to describe something that is not often found or experienced. Suitable in both spoken and written contexts. Avoid using in very informal situations.
