Misconceptions are pretty common. The lack of knowledge is the biggest reason behind them. If you are not a doctor or a student of biology, there is a high chance you will point to the wrong bone when asked you the location of the humerus in the body. However, some misconceptions are common among large groups of people. They are either spread through a TV show or a social media post. When we believe people on the internet, more than actual experts, such misconceptions are bound to happen. Although it is okay to not know about some things, we should always keep trying to educate ourselves.
Many people think that Spanish and English are related due to the number of similar words they have but they are incorrect. Although both belong to the same family of vernaculars, they are not quite similar. Spanish originated from Latin, while English did not. The similarities between the two exist because they are both famous vernaculars and come into contact with each other quite frequently. Many people would be surprised to learn that German and English are closely related. They have many common features which appear more clearly to linguists than the speakers of the two vernaculars.
