Is 'Windy' an Adverb in 'It Is Windy'?

The sentence, "It is windy," might seem to some as containing an adverb, but upon closer inspection, it is actually an adjective. This confusion often arises due to our intuitive understanding of how certain words function in sentences. Let's break down this grammatical conundrum and explore the nuances of adjectives and adverbs.

Understanding Adjectives and Adverbs

Adjectives describe or modify nouns or pronouns. They can also modify other adjectives. For example, in the phrase "a windy beach," "windy" is describing the noun "beach." Similarly, "a windy day" and "a windy speech" use "windy" to describe what the day or the speech is like.

Adverbs, on the other hand, modify verbs, adjectives, or other adverbs. They describe how, when, or why something happens. An adverb ending in "-ly" is a clear indicator, such as "quickly" or "beautifully." However, not all adverbs end in "-ly" (e.g., "fast").

The Sentence 'It Is Windy'

Let's examine the sentence "It is windy" in detail. Here, "windy" is modifying the pronoun "it." In this case, "it" refers to the weather or the prevailing conditions. Since "windy" is describing the state or condition of "it," it is functioning as an adjective, not an adverb.

The verb "is" in this sentence is a linking verb that connects the subject "it" to the predicate adjective "windy." Linking verbs typically take adjectives as complements. For instance, in "He is tall," "tall" is the complement that describes the subject "He." Similarly, "It is windy" is stating a condition or state of being, and thus "windy" serves as an adjective.

Subject Complements and Adjective vs. Adverb

Subject complements are parts of the predicate that come after a linking verb and describe the subject. Adjectives and adverbs can function as subject complements, but they do so in different ways. Adjectives describe a noun or pronoun, while adverbs describe verbs. In "It is windy," neither "it" nor "windy" is a verb. Instead, "windy" is providing additional information about "it" (the weather).

Consider the following examples:

Adjective as Subject Complement

"The sky is cloudy." Here, "cloudy" is an adjective that describes the state of the sky.

Adverb as Subject Complement (Incorrect)

"*The sky is cloudily." While "cloudily" would be an adverb, it doesn't make sense in this context to describe the sky (as a noun) with "cloudily."

Common Errors and Clarifications

Often, students or speakers make the mistake of using an adjective where an adverb is needed, or vice versa. For instance, saying "The wind is blowing windy" instead of "The wind is blowing strongly" can highlight this confusion. Adjectives like "windy" describe the noun (conditions of the wind) rather than the action of blowing itself.

Real-World Examples

Let's look at some real-world examples to further illustrate this:

Example 1: Modifying a Noun

"The weather is windy." Here, "windy" describes the weather, making it an adjective.

Example 2: Modifying a Verb (Correct)

"The wind blew strongly." In this case, "strongly" is an adverb modifying the verb "blew," describing how the wind blew.

Conclusion

In conclusion, "windy" in the sentence "It is windy" is an adjective because it modifies the noun substitute "it" (the weather). Understanding the difference between adjectives and adverbs is crucial for clear communication and accurate sentence construction. By recognizing their functions, we can ensure that our writing and speech are both precise and effective.
