Learning Languages by Practices Phrases and sentences

Practicing is the best way to learn a different language, especially by practicing commonly used phrases in the language. Having a list of everyday phrases that people use will both help learners practice the language and also getting to know useful questions and responses. For example, one can practice Vietnamese phrases by learning a list of common sentences available online from some useful websites such as phrasemodo.com, where language lists are always growing and expanding. Or if one wants to learn Spanish, Japanese or Chinese, those languages are also available as well. Of course, socializing with people and friends that speak the language you are trying to learn is a good way to learn while you practice.

The other way is taking a class for a language that can also help you learn and practice among classmates. Either way practitioners can always benefit from online resources that supplements text book and course work.
