Grammar is the way or the rule we arrange words to make proper sentences.

We need those rules in the same way as we need the rules in a game.

Language: Language is a ​system of ​communication consisting of ​sounds, words, and ​grammar, or the ​system of ​communication used by ​people in a ​particular ​country or ​type of ​work: 

Literature: Literature is the entire body of writings of a specific language, period, people, etc. Literature is an art of the written word that introduces the reader to something new, or shows them a different side of a familiar perspective, whether in the form of a novel, poem, memoir or short story. Literature seeks to create emotions and or reveal to the reader the emotions of the writer.

Literature refers to texts, books, pieces of writing.

Word: word is the basic unit of language. Words can be classified according to their action and meaning. A word works as a symbol to represent/refer to something/someone in language to communicate a specific meaning. Example: ‘love’, ‘cricket’, ‘sky’ etc.

Words are two types-vowels and consonants.

Vowels are words that start with a, e, I, o, and u. All other words starting with other letters are called consonants.

Determiners: Articles:
Almost every sentence that you say, hear, read, or write contains articles, yet most people cannot define what role these words play in the English language. Nouns are often preceded by the words the, a, or an. These words are called articles or DETERMINERS. They indicate the kind of reference which the noun has.
