From igloos to imagination, nouns that start with the letter "I" provide a certain level of fancy to our writing. They can be iconic or likened to an imbecile. It doesn’t matter the direction. These nouns are an important bunch. Let’s do a quick review of nouns themselves and then explore the world of I-nouns.

What Is a Noun?

A noun is a person, place, thing, or idea. You’ll often see them come after an article, like "a," "an," and "the." They also like to stand as the subject of a sentence. For example, "The igloo was a hotel!”

Nouns can also be the object of a sentence. That means they’ll come after the verb. For example, "You need to adjust your ideology on that matter." Names, including people, cities, and more are also considered nouns.

Types of Nouns

Nouns function in many capacities. In fact, there are over 10 different types of nouns. Proper and common nouns are a popular bunch. If a noun is referring to a person or place, it’s likely acting as a proper noun (e.g. Margaret, Baltimore, Montana, Iceland, and the Capitol). An example of that would be, "Isabelle has gorgeous red hair."

Common nouns, on the other hand, refer to general, unspecified things. In the example above, Isabelle is a proper noun. But, if that line simply read, "That individual has gorgeous red hair,” you'd know the subject was a common noun. Unless they come at the start of a sentence, common nouns aren’t capitalized or specific.

That brings us to pronouns. It’s not uncommon to see both nouns and pronouns in a single sentence. For example, “Isaac handed the glass to her.” Along with these types of nouns, you’ve also got compound nouns (e.g., icebreaker and inkblot), countable nouns, possessive nouns, and more.
