To be able to hold a conversation you can learn some basic vocabulary and grammar rules. It is estimated that 88 percent of spoken dialogue in Spanish consists of 1000 most common words. This might not be a very difficult task to accomplish in a short span of time. However, rather than just learning a word, it is important to use them in your sentences. Every time you learn a new word immediately try to make as many sentences as you can using this word. This helps in remembering the word for a long time. You can even try to write them because your brain remembers better when you write something and it also becomes easy to recall these words.
Is self-learning possible? Yes, there are many options from the regular textbooks to online videos that can help you in self-learning. However, this might be a tedious process and there is a high possibility of getting diverted from the learning or just dropping it mid-way. Thus, finding a reliable tutor who can help with the language is the best option. You need not worry about timings as it happens with regular classes when you choose an online class because most of them help you fix a class at a time that suits you best.
There are many online platforms that are teaching you Spanish. Even as a beginner you can get the best results and learn Spanish at a good rate in a short span of time. It is very important to find a course that focuses more on speaking Spanish as this would help you learn the language faster. Depending on whether you prefer to learn in a group or individually you can find a course. However, if you choose a group session it is always a good idea to find something which has a limited number of students so that the trainer is able to interact with and engage all of them. An individual session gives you the advantage of complete attention of the tutor on you and you can ask any question without any hesitation.
To choose a good online platform you can check their website and read testimonials of other students who have taken the course to ensure that you get the best for the money that you spend.
As a beginner to learn Spanish, just speak, speak and speak and do not worry about mistakes. Our mistakes always help us learn better.
