Because English and German are both Germanic languages there are many cognates; meaning that words in German and English are related and you can guess the meaning.
Examples are:
backen – to bake
das Wasser – water
die Schule – school
However, there are words in English that have been taken directly from German and kept the German spelling. We call these words loanwords (which interestingly is a direct translation of the German „Lehnwort“.)
I have compiled a number of these words, some very common, others more specific to a certain topic. I have also included some words that might be spelled more “English”, or might be partially translated.
Here are two examples. You can read more about it on my blog here:
