I believe English as we know it is an amalgamation of Germanic and latin(French) roots.
Explains why we have so many cognates with both languages and many inconsistencies in spelling and pronunciation.
One tidbit that lingers in this old guy is that the “split infinitive” is not possible in Latin, so the knuckle-buster monks who taught English to native speakers of English claimed that splitting the infinitive is improper. What ‘holes. :^)
Beef and mutton are Old English.
There’s probably more rattling around in here, but that’s all that comes to mind.
