用法筆記
Frequently followed by 'of + the items being grouped' and 'by/according to + the criterion used' (categorisation of patients by age; categorisation of risks according to severity). Common in academic, legal, and bureaucratic writing; in everyday speech 'sorting' or 'grouping' usually replaces it. The American spelling is 'categorization' with a 'z' — the noun is identical in meaning, only the spelling differs.
