Effective language learning follows certain principles. At the most basic level, you must make sure that your input and your output are balanced. Input refers to how much of the new language you listen to and read on a daily basis. Output is the way you train yourself to speak.
Input in your language program.
The two most important things you can do here are to listen to the new language intensively, and to read as much of it as possible. Yes, it is useful to study basic grammar and vocab, but it must be reinforced by a lot of listening and reading. There are so many rules of syntax and so many special cases and exceptions, that unless you are massively exposed to them, they will never sink into your long term memory and automatic recognition. Nowadays there are many (free or very inexpensive) foreign language podcasts available on the internet. If you choose them well, they will be your primary tool to develop your capacity to hear/read and understand a new language.
Output in the language program.
Before you start to speak in a language, you need to feel reasonably comfortable with your pronunciation. You don’t need to be perfect but you want to feel confident and competent.
Once you can read and sound the language comfortably, and once you have read/heard a fair bit of it (input), it is time to try your hand, or rather your tongue at making sentences. It is always useful to learn basic greetings and daily life utterances. It is a good place to start. Then, as you learn different points of grammar and particularly verb tenses, you can begin by translating the examples back into the new language. This is a great way of testing whether you actually have learned the new patterns. Then try you hand at making little conversations. For example, once you have learned the past tense, see whether you can describe an enjoyable vacation you took in the past, or an interesting life event. Verbs will normally control your ability to speak a language.
This is just a brief introduction, but make sure that you cover both bases: listening/reading and speaking practice. Whatever method you use they will have to be balanced. Good luck on your learning journey.
