The British English term, "short trousers", is used, only for shorts that are a short version of ordinary trousers (i.e., "pants" or "slacks" in American English). For example: tailored shorts, often lined, as typically worn as part of a school uniform for boys up to their early teens, and by servicemen and policemen in tropical climates. "Shorts", used unqualified in British English, refers to sports shorts, athletic shorts, or casual shorts; the last is nowadays commonplace in warm weather in the UK. Shorts are also known as "half pants" in India.
