dread: [12] Old English had the verb ondrǣdan ‘fear’. Its first syllable is generally taken to be the prefix *and- ‘against’, which is related to German ent- ‘away, un-’ and Greek anti- (source of English anti-) and appears also in English answer. The second part, however, remains a mystery. There are one or two related forms in other West Germanic languages, such as Old High German intrātan, but where they come from has never been established satisfactorily. By the end of the Old English period this obsolete prefix had shrunk to a- (adread survived until around 1400), and in the 12th century it started to disappear altogether.
