Etaoin Shrdlu, any idea if the ge- past tense marker in Modern German is related somehow to the Old English prefix (and if not, where it actually came from)?Or y -, as in 'yclept', still in humorous use.
In Berlin dialect, G is often pronounced like (German) J, so gekommen would be pronounced jekommen.
It's the same prefix. The only difference is that it was far more productive in Old English than it is in modern German and not as grammaticalized (i.e. while it is sometimes appended to the past participle in Old English, that isn't a mandatory rule as in German). But remember that ge- is highly lexicalized in German as well, being a very common prefix with verbs (e.g. gefrieren), adjectives, and nouns, just like in Old English.
