Along with globalization, the modern world has a tendency to learn foreign languages. A modern man, keeping up with the times, is trying to develop, improve and keep up with his fellow foreigners, while becoming a bilingual. Learning languages helps not only be a notch one step ahead of your rivals (because now there is crazy competition among professionals on the market), but also successfully move up the career ladder.
If you have decided in favor of learning the culture of other nations by learning the language of a country, then congratulations. As they say, how many languages you know, how many times you are a person. One of the fundamental principles of language learning is the mastery of its grammar. So let's figure out what grammar is.

It is no secret to anyone that with the development of mankind, language also developed, the forms of words and, of course, grammar changed. Now everyone has free access to books of various levels of workload, designed for different age categories, and he has the opportunity to discover what grammar is. Speaking directly about the grammar of the English language, it can be noted that it is somewhat different from such a native grammar of the Russian language. Over time, the verb in the Russian language is no problem. For example, the phrase “I am writing an article” sounds the same both when it comes to an action that is constantly repeated (“I write an article every night”), and if they talk about the present (“I am writing an article now”). In other words, in the sentences “Every evening I write an article about work” and “I now write an article” the same verb is used. As for “now” and “every evening”, these are just words-additions to the verb form “I write”. I think you already appreciated what grammar is.

As for the
case endings, it’s easy to deal with them, because they simply do not exist in English. There is no difference in endings between words in the feminine and masculine gender. But a complete mess with the
forms of the verb. English grammar will never cease to amaze you and at the same time please you. For example, in the sentences “I am waiting for you now”, “I am waiting for you in the afternoon” and “I am always waiting for you here” in the English version you need to use the verb in three different tense forms!
As you already understood, the academic grammar of the English language requires special attention from the student and, of course, perseverance, practice and practice again. Without it, communication is impossible. Talking using the wrong temporary forms, you will remain an incomprehensible foreigner, as he simply will not be able to figure out what idea you want to convey to him.

Reading books (newspapers, magazines), listening to audio in English, studying grammar as the basis of a language, practicing with a native speaker on Skype or in courses will help you achieve good results in learning a foreign language. Do not try to find out what grammar is by learning the passages from the textbook yourself. In this way, you will not achieve the result. For example, if you like to write, then try to write an essay using recently learned words and, of course, grammar rules. And, finally, the most effective way - go abroad to a language camp, under an exchange program, or just travel and combine business with pleasure.
