英語の語源
stream
stream: [OE] A stream is etymologically something that ‘flows’. The word comes from a prehistoric Germanic *straumaz (source also of German strom, Dutch stroom, Swedish str?m, and Danish str?m). This in turn was derived from the Indo-European base *sreu- ‘flow’, which has also given English catarrh, diarrhoea, and rheumatism. Non-Germanic relatives of stream include Polish strumyk ‘brook’ and Sanskrit srotas- ‘stream’. => catarrh, diarrhoea, rheumatism
stream (v.)
early 13c., "to flow copiously," from stream (n.). Transitive sense "discharge in a stream" is from late 14c. Related: Streamed; streaming. Compare German str?men, Dutch stroomen, Danish str?mme, all verbs from nouns.
stream (n.)
Old English stream "a course of water," from Proto-Germanic *straumaz (cognates: Old Saxon strom, Old Norse straumr, Danish str?m, Swedish str?m, Norwegian straum, Old Frisian stram, Dutch stroom, Old High German stroum, German Strom "current, river"), from PIE root *sreu- "to flow" (see rheum).
From early 12c. as "anything issuing from a source and flowing continuously." Meaning "current in the sea" (as in Gulf Stream) is recorded from late 14c., as is the sense of "steady current in a river." Stream of consciousness in lit crit first recorded 1930, originally in psychology (1855). Stream of thought is from 1890.
