English has this weird dichotomy where most of the words in a typical sentence are Germanic, while most of the words in the dictionary are French.

Fun fact: according to a quick count by AI using web search, the previous sentence contains 21 words of Germanic origin, 2 of Latin origin, 2 of Greek origin and 1 of French origin. Also the etymology of the word Germanic is Latin, while that of the word French is Germanic

Norman French due to the Norman invasion of 1066 resulting in Old English evolving into Middle English. You can see that in the words for animals vs meats (cow and boef/beef, sheep and mutton, etc.) where the Germanic people raised the sheep and the Norman aristocracy ate them.

A lot of the more common and simpler words are Germanic, as is the grammar (e.g. compound words like cupboard).

Depends is bratwurst a German word or an English one? You will hard pressed to find an American that doesn’t know thr word and what it means. You can buy them at just about any grocery store and they are a staple of many restaurants.

At some point the word becomes both. Sourced from its mother language and maybe even still meaning the same thing in both, but no less an English word than any other at this point.

They are not. Quite a few have Latin roots and the like that corresponding French words share.

French english speakers usually have a quite good vocabulary. Getting to the point of speaking english is a milestone that's quite difficult for french speakers though.

English is the PHP of human languages.

True. I'm French native but my English is better (educated in Australia) so this created a weird situation for me where I got 14/20 for advanced words and 19/20 for expert words.

To be fair, I think I messed up a few advanced words by accident but I think the general pattern would hold because many of the expert level words seemed to have French root. So it felt like it got easier towards the end for me. Grandmaster words were a bit weirder on the whole.

I'm an engineer and read mostly non-fiction so this probably explains the gap too.

English also has a ridiculously high fraction of Latin too.
