Basic grammar refers to the building blocks of language, including the parts of speech (e.g. nouns, verbs, adjectives, adverbs), as well as the rules of syntax (e.g. how to form sentences).
Learning basic grammar is essential for being able to communicate effectively in any language. It can also be helpful in understanding how language works, and in learning new languages.
There are many resources available for learning basic grammar, including books, websites, apps, and courses. Some of the most popular grammar books include "The Elements of Style" by Strunk and White, "The Oxford Dictionary of English Grammar" by Levey and Hoberman, and "The Cambridge Grammar of the English Language" by Huddleston and Pullum.
In addition to books, there are also many websites and apps that can be used to learn grammar. Some of the most popular include Grammarly, Duolingo, and Babbel.
Courses are also available for those who want to learn grammar. Many colleges and universities offer English as a Second Language (ESL) courses, which can be helpful for those who are learning English as a second or third language. There are also many online courses available, such as those offered by Udemy and Lynda.
