powerful explosive consisting of a mixture of nitroglycerine with an absorbent, 1867, from Swedish dynamit, coined 1867 by its inventor, Swedish chemist Alfred Nobel (1833-1896), from Greek dynamis "power" (see dynamic (adj.)) + -ite (2). Figurative sense of "something potentially dangerous" is from 1922. Positive sense of "dynamic and excellent" by mid-1960s, perhaps originally African-American vernacular.
Laureat poete is first found in "Canterbury Tales" (in reference to Petrarch -- Fraunceys Petrak); it also was used in Middle English of Aesop and, by early 15c., of Chaucer. Inverted form poet laureate, in imitation of Latin word order, is from c. 1400 in English); the first official one probably was Ben Jonson (1638), though the first recorded one was Dryden (1668). Extended 1947 to Nobel prize winners. As a noun, 1520s, from the adjective or from a mistaken reading of poet laureate. Related: Laureateship (1732), laureation.
