More evidence that English is a Germanic language ...
Let's go back in time a little, to the language of Chaucer and Shakespeare, and compare archaic English with modern English and German.
I have - I have - ich habe
you have - thou hast - du hast
she has - she hath - sie hat
^^^ This clearly isn't borrowed. It shows how English and German started off quite close and have grown apart for various reasons.
Let's go back further, to Old English. English used to have 4 grammatical cases, again just like modern German.
the king - se cyning - der Koenig
to the king - to tham cyning - zu dem (zum) Koenig
^^^ Look at Old English's version of 'the' in the dative case. It ends in -m, just like German.
