How it is used
- Two uses: adjective/noun 'abnormal/anomaly' - 数据异常 (shùjù yìcháng) abnormal data; and adverb 'extremely/exceptionally' - 异常兴奋 (extraordinarily excited).
- The adverbial sense is intensifying ('unusually X'); context tells them apart.
- Contrast 正常 (normal). Technical and emphatic registers both common.
