dynamic [dynamic 词源字典]: dynamic: [19] Greek dūnamis (a word of unknown origin) meant ‘strength’. It was used by the Swedish chemist Alfred Nobel in 1867 to form the name of the new explosive he had invented, dynamite. From it was derived the adjective dunamikós ‘powerful’, which French adopted in the 17th century as dynamique, and English acquired it in the early 19th century. Related to dúnamis was the verb dúnasthai ‘be strong’ or ‘be able’; from this was derived the noun dunasteíā ‘power, domination’, source, via French or late Latin, of English dynasty [15].

Part of the same word family is dynamo [19], short for dynamo-electric machine, a term coined in 1867 by the electrical engineer Werner Siemens.

aerodynamic (adj.): also aero-dynamic, 1847; see aero- + dynamic (adj.). Compare German aerodynamische (1835), French aérodynamique.

anodyne (adj.): 1540s, from Medieval Latin anodynus "pain-removing, allaying pain," from Latin anodynus "painless," from Greek anodynos "free from pain," from an- "without" (see an- (1)) + odyne "pain," a word perhaps from PIE root *ed- "to eat" (source of Lithuanian edžioti "to devour, bite," edžiotis "to suffer pain;" see eat). In old slang, frequently a euphemism for "death;" as in anodyne necklace "hangman's noose."
dynamic (adj.): 1817 as a term in philosophy; 1827 in the sense "pertaining to force producing motion" (the opposite of static), from French dynamique introduced by German mathematician Gottfried Leibnitz (1646-1716) in 1691 from Greek dynamikos "powerful," from dynamis "power," from dynasthai "to be able, to have power, be strong enough," which is of unknown origin. The figurative sense of "active, potent, energetic" is from 1856 (in Emerson). Related: Dynamically.
