What Is a Part of Speech?
Before dissecting the parts of speech of "what," it's helpful to revisit what parts of speech are in general. Parts of speech are categories that describe the function of words in sentences. These include nouns, verbs, adjectives, adverbs, pronouns, conjunctions, prepositions, and interjections. Each category has a specific role that helps construct meaning and maintain sentence structure. When we talk about "what," it’s important to recognize that it doesn’t belong to just one part of speech. Instead, it can function in several capacities, such as a pronoun, determiner, or even an adverb, depending on context.The Pronoun Role of What
One of the most common parts of speech of "what" is as an interrogative pronoun. In this role, "what" is used to ask questions about things or ideas rather than people.Interrogative Pronoun
- What is your favorite book?
- What happened at the meeting yesterday?
- What do you want to eat?
Relative Pronoun Usage
Besides asking questions, "what" can function as a relative pronoun, introducing a clause that provides more information about a thing or idea:- I don’t understand what you mean.
- She gave me what I needed.
- Tell me what happened.
What as a Determiner
Another important part of speech of "what" is its use as a determiner. In this case, "what" modifies a noun by asking for specific information about it.Interrogative Determiner
When "what" comes before a noun, it functions as an interrogative determiner:- What time is the meeting?
- What color do you prefer?
- What book did you read?
Exclamatory Determiner
"What" can also be used to express exclamation, emphasizing the noun it precedes:- What a beautiful day!
- What an amazing performance!
- What a surprise to see you here!
What as an Adverb
Sometimes, "what" acts as an adverb, particularly in informal or poetic language, modifying adjectives or adverbs to express degree or intensity.Adverbial Use in Expressions
Although less common, "what" can modify adjectives or other adverbs to emphasize how much:- What a terribly cold day!
- I didn’t know what so suddenly happened.
- She is what remarkably talented.
Common Mistakes When Using What
Understanding the parts of speech of "what" helps avoid common mistakes, especially when differentiating between pronoun and determiner roles. For example, a learner might say, "What is your name?" (correct) but confuse it with "What your name is?" which is incorrect word order. Also, mixing up "what" with "which" can cause confusion. While both can function as interrogative determiners or pronouns, "which" typically implies a limited set of options, whereas "what" is more open-ended.Tips to Master the Use of What in Different Contexts
Mastering the parts of speech of "what" requires practice and attention to sentence context. Here are some tips to help:- Identify the function: Ask yourself if "what" is replacing a noun (pronoun), modifying a noun (determiner), or intensifying an adjective/adverb (adverb).
- Look at sentence structure: In questions, "what" often starts the sentence. In relative clauses, it appears in the middle.
- Practice with examples: Write sentences using "what" in different roles to become comfortable with its versatility.
- Listen and read: Pay attention to how native speakers use "what" in conversations, books, or media to internalize its functions.
Why Knowing the Parts of Speech of What Matters
Grasping the parts of speech of "what" is more than grammar trivia—it's a key to enhancing your communication skills. Because "what" is so common in questions, statements, and exclamations, understanding its multiple roles can clarify meaning and improve both writing and speaking. For English learners, this knowledge helps build confidence when forming questions or expressing surprise. For writers and editors, it aids in crafting sentences that convey precise meaning and tone. Moreover, recognizing how "what" functions aligns with broader language learning goals, such as mastering sentence structure, improving comprehension, and expanding vocabulary.Exploring Related Words and Their Functions
While focusing on the parts of speech of "what," it’s useful to consider related interrogative words, often called WH-words, such as "who," "which," "where," "when," and "why." Like "what," these words serve as pronouns or determiners in forming questions and relative clauses. Learning their similarities and differences can deepen your understanding of question formation and sentence complexity in English. For example, while "what" asks about things or ideas, "who" is reserved for people, and "which" implies choice.Incorporating What into Your Everyday Language
Once you are comfortable with the parts of speech of "what," you can use it creatively to engage in conversations, write compelling narratives, or ask insightful questions. Try experimenting with "what" in different contexts:- Ask open-ended questions to invite detailed answers.
- Use "what" in exclamations to express emotion vividly.
- Employ "what" in relative clauses to add information smoothly.
