among: [OE] Gemong was an Old English word for ‘crowd’ – ge- was a collective prefix, signifying ‘together’, and -mong is related to mingle – and so the phrase on gemonge meant ‘in a crowd’, hence ‘in the midst, surrounded’. By the 12th century, the ge- element had dropped out, giving onmong and eventually among. A parallel bimong existed in the 13th century.
