单词 principle
释义

principlen.

Brit. /ˈprɪnsᵻpl/, U.S. /ˈprɪnsəp(ə)l/
Forms:

α. Middle English principel, Middle English principyll, Middle English pryncisple (transmission error), Middle English–1500s prynciple, Middle English–1500s pryncyple, Middle English– principle, 1500s pryncypull; Scottish pre-1700 prinsapell, pre-1700 1700s– principle.

β. Middle English princepal, Middle English principall, Middle English prinsipall, Middle English pryncipal, Middle English pryncypal, Middle English 1900s– principal (nonstandard); Scottish pre-1700 principall, pre-1700 (1900s– nonstandard) principal.

Origin: Probably of multiple origins. Probably partly a borrowing from French. Probably partly a borrowing from Latin. Etymons: French principe; Latin principium.
Etymology: Probably (with parasitic -l- ) < Middle French, French principe fundamental concept in a science (c1245 in Old French), origin, source, first cause (c1265), rule of conduct (mid 14th cent.), fundamental source from which something proceeds, fundamental truth used as a basis of further reasoning, important proposition in a discourse (all second half of the 14th cent. or earlier), precept (end of the 15th cent. or earlier), (in alchemy) one of several simple substances of which all bodies were believed to be composed (early 16th cent. or earlier), (in physics) component part, constituent (of matter) (1636), (in chemistry) element (1680; now rare) and its etymon classical Latin principium principium n. With the parasitic -l- compare Old French principle beginning, point of departure (late 12th cent. in an apparently isolated attestation), and also manciple n., participle n., syllable n., treacle n. In Middle English and Older Scots β forms are common, and probably result largely from association with principal n., principal adj., with which there has probably always been some semantic association (compare principal n. 4c, 7b, which could alternatively be interpreted as showing forms of the present word influenced by association with principal n.). (In modern use, especially from the 20th cent. onwards, misspellings of the noun as principal are common; compare also discussion at principal n.)Compare Old Occitan principi (15th cent. or earlier), principe (beginning of the 16th cent. or earlier), Catalan principi (14th cent.), Spanish principio (second half of the 13th cent. or earlier), Portuguese principio (14th cent.), Italian principio (beginning of the 13th cent. or earlier). With in principle at sense 4c compare French en principe (1792). With on principle at sense 4d compare French par principe (1755). Sense 8a is apparently not paralleled in French until later (1611 in Cotgrave).
I. Origin, source; source of action.
1.
a. That from which something originates or is derived; a source, an origin; the root (of a word, etc.). Now chiefly Philosophy and Theology.
