Know what your learning style is
This is the first thing you need to know when you start learning a language. Everyone has different ways of learning, especially when it comes to languages. You’ll need to determine whether you learn best with repetition, writing the words down, or listening to a native speaker speak.
Know if you assimilate your knowledge visually, auditorily or kinesthetically (internal sensation of body movements). There is a trick to knowing your category: choose two words from your native language and rewrite them several times. If you can remember it the next day, your ability to learn is probably visual. Otherwise, find someone who repeats these two words to you several times without seeing them yourself. If you can remember it the next day, you’re probably an auditory type. If that doesn’t work for you, read and write those two words, repeat them out loud, hear them spoken by someone else, associate memories and feelings with those words. If you can remember them the next day, you are probably a kinesthetic type…
If you have learned languages in the past, review what you have learned and find out what worked best for you. What helped you learn? And what didn’t help you? When you have determined this, you will be ready to learn this language.
Learn the pronunciation
Even if this language has the same alphabet as yours, that does not mean that the pronunciation is necessarily the same (so ask a Polish person to pronounce the letters CZ).
Most foreign language institutes offer free language learning tools, which include audio recordings to help you with pronunciation as well as a helpful pronunciation site (and free language learning services of quality  ).
Pay attention to grammar.
It is undoubtedly with the vocabulary the most important part of a language. “Marc wants Bridget to take him to the store” may convey an idea, but it’s not good French. If you don’t pay attention to grammar, you can be just as incomprehensible in another language.
See the structure of the language and how the genders are articulated (masculine, feminine, neuter). Understanding the structure of language will help you put words together as you expand your vocabulary.
Make sure you know how to ask questions, how to formulate affirmative and negative sentences in the past, present and future using the twenty most common regular and irregular verbs in the language.
Memorize thirty words and phrases each day. You will have retained 80% of the language within three months. Start with the most common words. Memorization alone is half the battle and there are different ways to remember something.
You can practice writing each word a dozen times, which will get you used to using that word.
Try using these words in a variety of different sentences. This will help you take the words in and remember them when you need them.
Remember to continue studying these words as you move on to memorizing other words. 4. Master the alphabet.
You’ll need to know what the letters look like and how they fit together, especially if you’re learning a language that works on a different alphabetic system (like Russian, for example).
Try to associate images with each letter and sound, so your brain will find an easy way to remember the letter and its accompanying sound. In Thai, for example, the letter “า” is pronounced “ah.” If you’re a boy, you can think of it as the sigh of relief that accompanies your peeing against a tree. These associations can be as simple as that or completely silly, as long as they help you remember  .
You should also get used to writing from right to left or top to bottom. Start simple and progress to more difficult readings like newspapers and books.
