单词 laboratory
释义

laboratoryn.

Brit. /ləˈbɒrət(ə)ri/, U.S. /ˈlæbrəˌtɔri/
Forms: 1500s– laboratory, 1600s labaratory, 1600s laboratorie, 1600s laboritary, 1600s labratory.
Origin: A borrowing from Latin. Etymon: Latin laboratorium.
Etymology: < post-classical Latin laboratorium workplace (12th cent. in a British source) < classical Latin labōrāt- , past participial stem of labōrāre labour v. + -ōrium -ory suffix1. Compare French laboratoire (1620), Catalan laboratori (1696), Spanish laboratorio (mid 17th cent.), Portuguese laboratório (1716), Italian laboratorio (17th cent.). Compare later elaboratory n.In sense 3 probably after French laboratoire (1757 in this sense). N.E.D. (1901) gives only the pronunciation (læ·bŏrătəri) /ˈlæbərətərɪ/. The British pronunciation with stress on the second syllable seems to have been first noted in the Encycl. Dict. (1895).

Later: one equipped for carrying out scientific experiments or procedures, esp. for the purposes of research, teaching, or analysis; (also) one in which chemicals or drugs are manufactured; an establishment in which such work is carried out. From the 19th cent. frequently with distinguishing word. In later use abbreviated lab. Cf. elaboratory n. 1.chemistry, physical, research, space laboratory, etc.: see the first element.
