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
A lot of the more common and simpler words are Germanic, as is the grammar (e.g. compound words like cupboard).
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.
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.
Latin isn't really any sort of parent to Old English afaik, even though the Romans ran Britain for a while.
