Common Contexts
This word is frequently used in formal or written contexts such as news reports, scientific observations, or serious conversations about unusual events. For example, "反常天气" (unusual weather) or "反常行为" (abnormal behavior).
Collocations and Patterns

- 反常现象 (unusual phenomenon): often used in scientific or economic contexts.
