You’re up-to-date on all the trends.
You watch trending hashtags obsessively.
You know all the latest fashions.
You’ve even single-handedly kept avocado farmers in business with your affinity for avocado toast.
But there’s one trend you may have overlooked: slang.
When you’re learning a language, staying on top of the latest slang can be a bit of a trick. After all, conventional courses usually only cover common, basic slang and often shy away from more colorful words and expressions altogether.
There’s no doubt that slang is pervasive in any language, and it’s possible you haven’t learned some of the more provocative terms native speakers might use.
Not only that, but as a language learner, you’ll have to keep the variations within your target language straight. For instance, Spanish slang, Mexican slang and slang from other Spanish-speaking countries varies quite a bit.
So how, then, can the trendy language learner possibly stay on top of the best slang in different languages? Luckily, there are plenty of great resources out there to keep your vocabulary up-to-date. Here are 30 books and websites that make learning slang a piece of cake!
Why Focus on Slang?
Slang is a type of informal language you won’t typically find in a textbook but is absolutely vital to clear communication. So while it may not be the first area of language you study, you should jump into it relatively quickly.
The primary reason to learn slang is that it’s overwhelmingly common. In any culture, there are an abundance of slang words and more being added periodically. If you’re studying English and you’re not keeping up, terms like “throw shade” or “on fleek” will go right over your head! Therefore, if you ignore it, you’re ignoring a significant part of your target language’s vocabulary.
Additionally, using slang can make you sound like a local. A lot of native speakers expect non-native speakers to sound unnatural due to their strict adherence to what they’ve learned from conventional textbooks. Using slang can set you apart and show you’re so much more than a common language student.
Finally, slang is often difficult to understand if you haven’t studied it. If you don’t make it part of your learning routine, you might not be able to figure out what these words mean based on context alone, and your fluency will suffer. You’re also more likely to miss some important parts of a conversation.
The Best Resources to Learn Slang in Different Languages
It’s important to note that slang is highly regional, so not all slang will be used in every place that speaks the language. If you’re targeting a particular region, you might try looking for slang from that specific region.
Here are some groovy resources for learning slang from popular languages.
