Not the best way to learn a language , but to increase your speed of talk.
The "swap" system which is very easy.You can use this method to learn any language.
Here is the method.
Just take a particular topic from the language, here for example modal verbs from german language.
step(1)find a sentence which contains the modal verb (the best when the sentence is long.).
eg:Ich will trinken.
step(2)change a word (noun,verb....)without changing the principle sentence.
eg: ich will spielen, ich kann trinken.
step(3)practice the sentence using lots of words.
you'll learn the structure so fast.
[I won't recommend you to avoid grammar.first learn grammar but when we practice the language use this method,this will help you to speak as fast as possible.]
