What Makes A Language Useful?

How useful a language is depends on several factors, all of which are personal to your own situation. These can include your personal goals and preferences, languages you might already speak or any business or educational goals you may have. Here are some things worth considering when you're trying to figure out what is the most useful language to learn.

Geography

Where do you live? Or where do you want to live? 

If you are thinking about moving house for work or simply for a change of scenery, you may want to learn a language that fits best with your new environment. For example, if you're moving to France, it would make sense to learn a bit of French, in Spain, Spanish and so on.

Alternatively, you could research the majority languages in your area, and see if one of those takes your fancy. If you are learning a language for personal enrichment, you will find tons of communities to get involved in. 

Career

Language skills are highly desirable in any field of business. Each industry is unique, but a second language will always look great on your CV. If you are looking to learn a language to help you prosper in business, you can research which companies are hiring in your area, and adjust your learning accordingly.  

Adaptability

Sometimes, it's important to pick a language depending on how versatile is it and how you can adapt it to your lifestyle or your work life. Choosing a language like Spanish or Arabic will be extremely versatile. Millions of people speak these languages worldwide, over several continents, and you're more likely to come across people who speak these languages in your everyday life.

Advantage

How often will you use the language? If it's a language you only use for travel purposes and only once or twice a year – is it worth learning? 

Perhaps you have a language that you can use every day. Maybe one that your friends or family speak, or one that you can use in your business. For example, even though a language like Mandarin Chinese is spoken by millions of people across the world, it might not be useful for you.

What Are Your Own Reasons For Learning a Foreign Language?

Languages are unique to everyone, and what is useful for someone else might not be useful for you. Let's take a look at some reasons why you might want to learn a new language.

Personal Reasons

You may be drawn to a foreign language because of how it sounds, for example, languages like French or Arabic are known to be melodic. 

Alternatively, you may be interested in learning more about a particular culture. Say you've always been interested in Russia and have a dream to live in St. Petersburg one day, you might want to start learning Russian for when that day comes. On the other hand, you might want to visit Rio during the carnival, hoping to meet some friendly Brazilians along the way.

Another reason may be love or friendship. You might have found a new friend or a new life partner who speaks a different language to you. You want to get to know them on a more personal level, speak to their family and discover their culture. 

Pragmatic Reasons

A pragmatic reason to learn a new language might be to open yourself up to new job opportunities. As we mentioned earlier, a new language is sure to be an asset in any career. 

Maybe you wish to study a foreign language at University, or you want to go study abroad for your whole degree. A new language, in this case, might be beneficial to help you get ahead.
