Word Origins Dictionary

- calculate[calculate 词源字典]
**calculate: **[16] *Calculate *comes from the past participial stem of the Latin verb *calculāre*, a derivative of the noun *calculus*, which meant ‘pebble’. This was almost certainly a diminutive form of Latin *calx*, from which English gets *calcium *and *chalk*. The notion of ‘counting’ was present in the word from ancient times, for a specialized sense of Latin *calculus *was ‘stone used in counting, counter’ (its modern mathematical application to differential and integral calculus dates from the 18th century).

Another sense of Latin *calculus *was ‘stone in the bladder or kidney’, which was its meaning when originally borrowed into English in the 17th century.
