each

英文词源

each

each: [OE] Each comes from Old English ǣlc. This, brief as it is, was in fact originally a compound adjective; it was descended from West Germanic *aiwō galīkaz, literally ‘ever alike’ (*aiwō is the source of English aye ‘ever’ [12], *galīkaz the source of English alike). ǣlc also formed the second element of an Old English expression, literally ‘ever each’, which has become modern English every.
=> alike, aye

each

Old English ælc (n., pron., adj.) "any, all, every, each (one)," short for a-gelic "ever alike," from a "ever" (see aye (2)) + gelic "alike" (see like (adj.)). From a common West Germanic expression *aiwo galika (cognates: Dutch elk, Old Frisian ellik, Old High German iogilih, German jeglich "each, every"). Originally used as we now use every (which is a compound of each) or all; modern use is by influence of Latin quisque. Modern spelling appeared late 1500s. Also see ilk, such, which.
