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.

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.
