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 ...
... and the part of Surfacelanguages snappily named Polylot People can 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 ...
... and this in essence sums up Polyglot People.
The sentences you will learn on Polyglot People are practical, such as:-
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
The sentences are informal.
They do not use slang or overly colloquial constructions.
There are benefits to this.
Firstly, you do not sound ridiculous;) and secondly in conjunction with a grammar book and your powers of decduction, you should be able to learn some grammar.
The sentences in (so far) eight different languages are identical (or at least similar).
Polyglot people uses a simple flashcard system to help you learn conversational sentences in groups of 10.
You can learn as many sentences as you want at once.
Once you have learnt ten sentences, the next ten become available and so on.
... to progress you have to get all the sentences correct in a simple audio test.
These will test you randomly on the sentences that you have learnt so far.
In other words, are you on your way towards polyglotism, or not ...;)
