This is amazing. I’ve never noticed the difference in the feel of Germanic vs Latinate-origin words before. What a cool observation. I know very little about linguistics, but I think you could split a few more words into your bold and italic categories. I think “with,” “their,” and “that” would also be from the Old English (I’m just thinking Icelandic cognates which indicate a Germanic origin — með, þeir, það).
It’s interesting to note the grammatical connections, too! It’s equally correct in English to say “Engineering Faculty” (from Germanic roots) or “Faculty of Engineering” (from Latinate/French roots).
