英文詞源

blade
blade: [OE] The primary sense of blade appears to be ‘leaf’ (as in ‘blades of grass’, and German blatt ‘leaf’). This points back to the ultimate source of the word, the Germanic stem *bhlō-, from which English also gets bloom, blossom, and the now archaic blow ‘come into flower’. However, the earliest sense recorded for Old English bl?d was the metaphorical ‘flattened, leaflike part’, as of an oar, spade, etc. The specific application to the sharp, cutting part of a sword or knife developed in the 14th century.
=> bloom, blossom, blow
blade (n.)
Old English bl?d "a leaf," but also "a leaf-like part" (of spade, oar, etc.), from Proto-Germanic *bladaz (cognates: Old Frisian bled "leaf," German Blatt, Old Saxon, Danish, Dutch blad, Old Norse blae), from PIE *bhle-to-, suffixed form (past participle) of *bhel- (3) "to thrive, bloom," possibly identical with *bhel- (2) "to blow, swell" (see bole). Extended in Middle English to shoulders (c. 1300) and swords (early 14c.). The modern use in reference to grass may be a Middle English revival, by influence of Old French bled "corn, wheat" (11c., perhaps from Germanic). The cognate in German, Blatt, is the general word for "leaf;" Laub is used collectively as "foliage." Old Norse blae was used of herbs and plants, lauf in reference to trees. This might have been the original distinction in Old English, too. Of men from 1590s; in later use often a reference to 18c. gallants, but the original exact sense, and thus signification, is uncertain.
