Your challenge is to start with the same basic linguistic building blocks as OTL's english (Galic, Anglo-Saxon, Old Norse, Norman French, Church Latin, etc) and with any POD you like, have them evolve into an alternate language that is completly uninitelligable to OTL english speakers.
That would be pretty recognizable. Hard to understand, but still intelligible.Spain defeats the English Navy in 1598 and holds on to England. Eventually, England and Spanish fuse into a new "English"
No Norman conquest, no vowel shift. English would end up far more German than it was OTL.
He probably did mean German. English today is still a Germanic language, but it's not very German. Old English on the other hand was quite German--weren't there mainland dialects of Saxon and Frisian with which it was mutually intelligible.I don't mean to be pedantic, but I think you mean "Germanic"; German and Germanic aren't the same thing. Sorry, just a little nitpick.

Old Low German (aka Old Saxon) is just as German as Old High German, and it's similar to Old English.Really? I never got that, in terms of comparing Old English to Old High German (aka "German" as popularly known). Now Old SAXON, on the other hand, I can see being lumped together with the Anglo-Frisian languages. But the Anglo-Frisian languages are Ingvaeonic, whilst High German is Irminionic (the difference being participation in the High German Consonant Shift, which almost no other Germanic language has participated in), so those aren't really "German" either, even though they're all "Germanic".

Any POD, any POD whatsoever before Old English starts shifting to Middle English, even if it's what if some random peasant in India stubbed his toe harder than IOTL in 1066. The Old English to Middle English shift was big enough and proceeded in ways that were unpredictable enough that all you need is butterflies to get pretty different grammar and vocabulary.

A Muslim win at Tours would probably butterfly away the Normans.
Possibly not. By Tours, the Muslims were at the end of their rope. They could hardly have advanced or conquered much further.
