I’m totally into passive learning, so when I was learning Spanish, I also changed my device (laptop and phone) languages to Spanish. The class I was taking was on the topic of technology, and I had to explain the parts of a browser. On Chrome, you could click the button that makes a new tab, and the tab title, in Spanish, would say Nueva pestaña which translates to New tab. What followed was an interesting comment by my professor: las pestañas could translate to either the word tabs, in a tech context, or the word eyelashes, when speaking about the human body. In other words, I learned that the same word could mean something else entirely when used in a specific context.
