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].

thermal (adj.)[thermal 词源字典]

1756, "having to do with hot springs," from French thermal (Buffon), from Greek therme "heat, feverish heat," from PIE *gwher- "to heat, warm" (cognates: Latin fornax "an oven, kiln," formus "warm," Old English wearm; see warm (adj.)). Sense of "having to do with heat" is first recorded 1837. The noun meaning "rising current of relatively warm air" is recorded from 1933.[t

heat: [OE] From an etymological point of view, heat is simply ‘hotness’ – that is, the adjective hot with an abstract noun suffix added to it. But the addition took place a long time ago, in the prehistoric ancestor of Old English. The suffix *-īn ‘state, condition’ was tacked on to the adjective *khaitaz ‘hot’ to produce *khaitīn, which eventually became modern English heat. The verb heat is equally ancient, and was independently formed from *khiataz (het, as in ‘het up’, comes from a dialectal form of its past participle).
