Dutch doesn't have the same intonation, has harsher pronunciations, and has a whole extra sound most English people struggle with (a rolled r).

The older generations also can't pronounce -thew very well as it's not a thing in Dutch, so struggle to pronounce my name, calling me Matchoo instead of Matthew. It still boggles my mind that my Mum would pick a name the Dutch can't pronounce.

The Dutch accent is also extremely noticeable to a native English speaker.

Ultimately, they're not the same at all as English is Germanic/Latin hybrid where half the words are French/Italian words, and half the words are Germanic/Dutch words.

Dutch is not.

You can usually tell by looking at the word and the end of the word.

Words like fantastic, manual, vision, aquatic, consume are all from -ique, -alle, -umme and will have similar words in French/Italian. The tend to be longer words with more syllables.

Words like mother, strong, good, are Germanic in root. The -er, -ong, -od words will all be similar to the German/Dutch words. Shorter, quicker to pronounce.

The language in section 1300 isn't much different from section 1400. Almost all of it is still good English today if you give the words their modern spelling:

Then after much time spoke the Master, and his words were cold as winter is. His voice was as the crying of ravens, sharp and shrill, and all that heard him were adread and durst not speak.

"I deem¹ thee to the death, stranger. Here shalt thou die, far from thy kin and far from thine own land, and none shall know thy name, nor none shall thee beweep."

And I said to him, with what boldness I might gather, "Why farest thou with me thus? What trespass have I wrought against thee, that thou deemst¹ me so hard a doom?"

"[Swie!]"² quoth he, and smote me with his hand, so that I fell to the earth. And the blood ran down from my mouth.

And I [swied],² for the great dread that was come upon me was more than I might bear. My heart became as stone, and my limbs were heavy as lead, and I []³ might no more stand nor speak.

The evil man laughed, when that he saw my pain, and it was a cruel laughter, without mercy or pity as of a man that hath no [rewthe]⁴ in his heart.

Alas! I should never have come to this town of Wolvesfleet! Cursed be the day and cursed be the hour that I first set foot therein!

¹ We still have this word in modern English, but the meaning is different.

² No idea what this word is.

³ I assume the ne in the text here is required by some kind of grammatical negative agreement with the rest of the clause. In more modern (but still fairly archaic) English, nothing goes here. In actual modern-day English, the grammar of this clause isn't really available for use, but it's intelligible.

⁴ This turns out to be the element ruth in ruthless, and a man with no ruth in his heart is one who is literally ruthless, without "ruth". It literally means "regret", but the use in the text clearly matches the metaphorical sense of the modern word ruthless.

...Nor shall I never it forget, not while I live!

... and that was a wife [= woman], strong and [stith]! She came in among the evil men and me [nerede] from their hands.

She slew the heathen men that me pinned, slew them and felled them to the ground. There was blood and [bale] enough. And they fell [and] lay still, for they [] might no more stand. And the Master, the [wraþþe] Master, he flew away in the darkness and was seen no more.

I said [to] her, "I thank thee, [leove] wife, for thou hast me [ineredd] from death and from all mine [ifoan]!"

Interestingly, nerede/ineredd has no descendant in modern English, but it's not difficult to understand in the passage, while leove and ifoan do have descendants, and in the case of ifoan the meaning hasn't changed, but they are harder to read.

In 1100 the idea of "just substitute the modern word in for the old word" starts to break down.
