It vs. Is: Know the Difference
By Shumaila Saeed || Published on February 15, 2024
"It" is a pronoun representing an object or animal, whereas "Is" is a verb form of "be," used with singular third-person.
Key Differences
"It" is a pronoun, used to refer to a non-human entity, animal, or inanimate object, often used to avoid repetition. "Is" is a verb, specifically the third-person singular present form of "be," used to indicate existence, identity, or a state of being.

"It" serves as a subject or object in a sentence, replacing a noun. For example, "The cat is sleeping; it looks comfortable." "Is" functions as a linking or auxiliary verb, connecting the subject to additional information. For example, "The weather is nice today."

Both words are commonly used in questions, but their roles differ. "It" is used to inquire about a specific object or situation, as in, "What is it?" "Is" forms questions about the state or identity of a subject, like, "Is it raining?"

"It" does not change form based on tense or number. "Is," however, changes based on tense (e.g., "was," "will be") and number (e.g., "are" for plural subjects).

"It" can often be replaced by the noun it represents without altering the sentence's meaning. "Is" cannot be removed without significantly changing or invalidating the sentence's structure.
