Are you ever (pleasantly!) surprised when you learn a word in your target language, only to find there are similarities to that word and one in English - or another language you’re familiar with that is not within the same language family? If you are an English speaker, you may find a lot of similarities within the Germanic tree, and likely several common words in the Romance languages. These are often easiest for us to remember by association. What about words that you stumble upon that you didn’t realize that were related to another language family?
An example for me is the word парасолька (par•ahs•OLK•ah) which sounds very much like the word we have for parasol, which has more roots in the Romance languages.
What are other examples across different language families that you find similarities in?
