Is Is Not Just a Word, It’s Also a Verb


In the English language, “is” may seem like a simple two-letter word, but it holds significant importance in sentence structure and communication. Not only is “is” a form of the verb “to be,” but it also serves as a linking verb that connects the subject of a sentence to a subject complement. Understanding the various roles and uses of “is” can enhance your grasp of grammar and improve your writing skills. Let’s delve deeper into the multifaceted nature of this seemingly unassuming word.

The Basics of “Is”

At its core, “is” is a form of the verb “to be” in the present tense when used with singular subjects like he, she, it, or a singular noun. This verb signifies a state of being or existence. When conjugated with different subjects, “is” adapts to match the subject in both singular and plural forms:

  • Singular: She is a doctor.
  • Plural: They are students.

Linking Verb Function

Beyond its role as a standalone verb indicating existence, “is” functions as a linking verb that connects the subject of a sentence to a subject complement. A subject complement provides more information about the subject, such as describing or renaming it. Here’s an example to illustrate this usage:

  • She is happy. (The subject complement “happy” describes the subject “she.”)

Common Alternatives to “Is”

While “is” is a frequently used linking verb, the English language offers a variety of alternatives that can add variety and nuance to your writing. Some common alternatives include:

  • Am: I am hungry.
  • Are: They are siblings.
  • Was: He was tired.
  • Were: We were happy.
  • Be: Let’s be mindful.

Using “Is” in Questions and Negations

When forming questions with “is,” the verb typically moves before the subject. For instance:

  • Is she a teacher?

In negations, “is” can be used with the word “not” to indicate the opposite. Consider the following example:

  • She is not feeling well.

Advanced Usage of “Is”

In more advanced grammatical structures, you may encounter progressive forms of “to be,” such as “is running” or “is eating.” These forms indicate ongoing actions in the present tense. Additionally, the perfect tense can be formed by combining “is” with the past participle of a verb, as in “is written” or “is spoken.”

Common Errors with “Is”

Despite its ubiquitous presence in the English language, “is” can lead to common errors, particularly when used in conjunction with plurals. Here are a few pitfalls to avoid:

  • Incorrect: The dogs is playful.
  • Correct: The dogs are playful.

Maintaining subject-verb agreement is crucial to ensure clear and concise communication in writing.

Enhancing Clarity with “Is”

To strengthen your writing, consider the following tips for effectively using “is” in your sentences:

  • Ensure subject-verb agreement: Match “is” with singular subjects and “are” with plural subjects.
  • Use subject complements: Utilize “is” as a linking verb to connect subjects with complements that enhance the description.
  • Vary your vocabulary: Explore synonyms and alternative verbs to “is” to prevent repetitive language use.

By mastering the various functions and nuances of “is”, you can elevate the quality of your writing and enhance your grammatical proficiency.
