👉 Articles in English grammar are used to indicate a shift in topic within a sentence or paragraph, typically by referring back to a previously mentioned noun or group of nouns. There are three types of articles: definite, indefinite, and possessive. Definite articles ("the") specify a particular noun that the reader or listener is likely to understand as being of interest or already known. Indefinite articles ("a" and "an") introduce non-specific nouns, indicating that the noun is not being referred to with particularity. Possessive articles ("my," "your," "his," "her," "its," "our," "their") show ownership or possession, clarifying which noun belongs to whom. Understanding and correctly using articles is crucial for clear and precise communication, as they help structure sentences and maintain coherence in writing and speech.
