I love how we are purifying the English language to rid it of its Romantic influence to be much more Germanic. But I was thinking, what if we took the next step and changed the grammar to be closer to Old English. There are two ways this could be done: Through a modern sound change filter, in which the sounds change to the proper patterns of today; or, try to mimic as best we can to the original Old English. I personally prefer the former so that is what I'm going to show below.
NOUNS: There are 4 cases(nominative, accusative, genitive, and dative) for singular, plural; strong and weak. In total, there are 16 noun declensions not including the three grammatical genders because it is very difficult to figure which gender a noun is. A weak noun ends in a vowel and a strong one ends in a consonant.
Strong Noun: cat, in anglish: puss
The puss eateth.
The dog hotfooteth the puss.
The dog eateth the pusses food.
The dog gave the pusse a wound.
The pusses eaten.
The dogs hotfooten the pusses.

Weak Noun: name

I gave the namen a lengthening.
The namen aren the same.
We changeden the namen.
The namene runen are ugly.
We gaven the namen lengtheninges.
