Online English Courses
Whoever said that all native English language speakers do not study English is wrong in many counts. Yes, people need to study the language, even native speakers because the language does have its own quirks and rule exceptions. For updated lessons one could take online English courses to learn the basics and even the advanced rules on the language.
Reasons for Studying
The main reason that people take online English courses is that they want to improve their understanding and knowledge on the subject for personal gain or to pass an English examination. There is this so-called "Business English" which is a branch of the language that deals with formal writing and English for use in one's career. Anyone could learn English and improve their careers.
Some people take online English courses to be certified as language instructors and be able to teach English to others - notably in ESL and EFL. In cases like this, the student gets to learn everything from the basic rules to word etymology to correct grammar to various exceptions when it comes to reading certain words or writing grammatically correct sentences.
One could study English to improve written application of the language - that is because spoken language is often very much less formal than written language.
Finding a Course
There are, of course, hundreds of online English courses that any student could choose from. Many will involve common grammar rules that may sometimes lead to confusion when used in a sentence. For instance, the contraction of "it" and "is" - "it's" - is often used in place of "its", an adjective as in "The cat and it's bell" which should actually be "The cat and its bell".
Various courses also deal with translation lessons - especially important for non-English speakers. For instance, although a lot of Spanish words are "borrowed" in the English language and vice versa, both languages are very much different from each other in terms of word spelling, usage, pronunciation, and grammar. Thus, for translation to be effective, not only will the student learn more on course English dictionary but also correct grammatical rules. As an example, "Have a nice day" translates to "Tenga un día agradable" instead of the "Tenga un agradable día" that it would have been for a word-for-word translation.
Getting confused? Do not be. English grammar rules and translation to other languages can sometimes seem daunting but learning them step by step through online English courses can make them become easier.
