4- bab.la

bab.la is a language project by Andreas Schroeter and Patrick Uecker. The idea has been on Andreas' mind for quite some time. During his high school and university years he lived in Canada, France, Sweden and the USA. He noticed that just knowing the exact translation often doesn't really help. You really need to "live" the language to come up with the right word. Andreas has been collecting dictionaries from different languages for a long time.

Putting the things together was just a natural step: Starting a portal where language lovers can meet and exchange their ideas and learn languages from each other. Who is a better teacher than a native speaker who likes to share his knowledge? And Patrick is our language expert regarding Pascal, C++, Java, Prolog, LISP, SQL, PHP, JSP and ASP. Thanks to him and his language skills this portal is alive today :-)

The language portal bab.la is a free online platform for language lovers and an online community of global citizens. The site has 44 dictionaries for 28 languages, blog articles about life abroad, language games and quizzes, verb conjugation for 12 languages, phrase books for university, business or travel, an internship platform and many other language-related products.
