Becoming a polyglot and speaking multiple languages fluently may be beyond most of us, both in terms of time and inclination, but still it sounds pretty cool.
The part of Surfacelanguages snappily named Polylot People can/may/will help you.
It might not be possible to *dominate* twenty languages, but it should be possible to learn 500 sentences in many of them and so be able to ask a bit about other people, say something about yourself and so on.
You will learn sentences like:-
Where are you from?
My skype ID is ...
How was your week?
We can talk tomorrow if you want
I went out at 6 o'clock in the evening
Have you been to England?
I went to Italy three years ago
Unfortunately I don't know
Very funny ...
I live near the centre of Berlin
It is of course, all free, like the rest of Surface Languages, so Sign up and give it a go.
