Why learn a language?
Even a little knowledge of the language can make a difference in attitude when you meet people from other countries. Speaking another language helps to break down barriers. Languages can build bridges.
Work and business
It can help you give an added advantage in your career if you work for an international firm or a company with international customers or contacts.
Music, film, arts and culture
If you like literature, fims or music from other countries, learning the language will help your appreciation and understanding.
For a challenge
You can learn a language in short, bite-sized sessions and you’ll enjoy a sense of satisfaction from achieving short-term goals, such as learning how to say hello, introducing yourself or numbers 1-10.
