If you have ever paused while writing or speaking and asked yourself what part of speech is these, you are asking one of the most practical questions in English grammar. In short, these is a demonstrative word that functions either as a demonstrative determiner—traditionally called a demonstrative adjective—or as a demonstrative pronoun, depending on how it is used in a sentence. The word these appears constantly in daily conversation, academic writing, and professional communication, yet its grammatical label often confuses learners and native speakers alike. Understanding this distinction is essential for building clear, correct sentences and avoiding common errors in subject-verb agreement and noun modification Small thing, real impact..
What Part of Speech Is These? The Direct Answer
The most accurate answer is that these belongs to a small category of words known as demonstratives. In modern grammar, it is classified as a demonstrative determiner when it comes before a noun, and as a demonstrative pronoun when it stands alone and replaces a noun. Older grammar textbooks may refer to the determiner use as a “demonstrative adjective,” but the function remains the same: these points to specific people, places, things, or ideas that are plural and relatively near to the speaker or writer.
Good to know here that these is not a noun, verb, adverb, preposition, or conjunction. It does not name a person or thing on its own when used as a determiner, nor does it express action or describe how something happens. Its sole purpose is to demonstrate or indicate which plural items are being discussed That alone is useful..
These as a Demonstrative Determiner
When these appears directly before a plural noun, it acts as a demonstrative determiner. Its job is to modify the noun and specify which particular items are being referred to. Because these is plural, the noun that follows must also be plural.
Examples:
- These students passed the exam.
- Can you hand me these documents?
- These cookies taste delicious.
- I have not seen these movies before.
In each sentence, these comes before a plural noun—students, documents, cookies, movies—and tells the reader exactly which ones are being discussed. The word also implies physical or temporal proximity. The items are near the speaker, either in space, time, or context. If the items were far away, the speaker would likely use those instead Surprisingly effective..
These as a Demonstrative Pronoun
These can also function as a demonstrative pronoun. In this role, it does not modify a noun because there is no noun following it. Instead, these stands alone and replaces a plural noun that has already been mentioned or is understood from context Most people skip this — try not to. Nothing fancy..
Examples:
- These are my favorite books.
- I do not want those; I want these.
- Look at these! They are amazing.
- These were the best days of our lives.
In the first sentence, these replaces the noun phrase “my favorite books.” The reader understands what these refers to because of the surrounding context or previous conversation. When these acts as a pronoun, it can serve as the subject or object of a sentence, just like any other pronoun That's the whole idea..
How to Tell the Difference
Distinguishing between the determiner and pronoun uses of these is simple if you look at the word that follows it.
Use these as a demonstrative determiner when:
- A plural noun immediately follows these.
Use these as a demonstrative pronoun when:
- No noun follows these, and the word stands alone to represent a plural noun previously mentioned or implied.
Examples:
- These are the keys you left on the table.
- I prefer these over the other options.
- These were the reasons we decided to move.
In these cases, these functions independently, replacing a noun phrase without needing a noun to follow it. The meaning relies entirely on context. Take this: in the sentence These are the keys, the word these refers back to the specific keys mentioned in the prior sentence, eliminating the need to repeat the noun Turns out it matters..
Contextual Proximity and Emphasis
The choice between these and those often depends on proximity—both physical and conceptual. Those, by contrast, suggests distance or separation. These typically signals closeness, whether spatial (the book on this table) or temporal (the events of these days). Still, in writing or formal speech, the distinction can blur when context overrides physical proximity.
- These arguments are more compelling than those presented earlier.
Here, these refers to ideas just discussed, while those points to a prior set of arguments. The proximity is conceptual rather than spatial, but the contrast remains clear.
Common Errors and Clarifications
A frequent mistake is using these with singular nouns, which is grammatically incorrect. Practically speaking, since these is inherently plural, it cannot modify a singular noun. *
- ✅ *This apple is delicious.For example:
- ❌ These apple is delicious. / *These apples are delicious.
Counterintuitive, but true Turns out it matters..
Similarly, these should not be confused with the possessive pronoun theirs. While these points to specific plural items, theirs indicates ownership:
- These are my friends. (referring to specific people)
- *Theirs are the friends I met yesterday.
The Role of Context
Context is critical in determining whether these acts as a determiner or pronoun. For example:
- *What are those boxes?In conversation, speakers often rely on shared knowledge to clarify meaning. *
- *These are the ones I packed.
Here, these replaces the noun phrase “the boxes,” relying on the prior question for clarity. Without context, the sentence might feel incomplete, but in practice, the connection is seamless Not complicated — just consistent..
Conclusion
Understanding the dual roles of these—as a demonstrative determiner and pronoun—is essential for precise communication. Worth adding: as a determiner, it modifies plural nouns and specifies proximity, while as a pronoun, it replaces entire noun phrases to avoid redundancy. Plus, recognizing the structure and context in which these is used allows writers and speakers to convey ideas with clarity and intent. Mastery of this distinction not only improves grammatical accuracy but also enhances the ability to craft nuanced and effective language, whether in casual dialogue or formal writing The details matter here..
By practicing these principles and remaining mindful of common pitfalls, communicators can make sure these functions as a precise tool rather than a source of ambiguity. Whether anchoring a sentence to the immediate present or drawing a sharp contrast with what came before, the word carries a weight disproportionate to its single syllable. In the long run, the effective use of demonstratives like these reflects a broader command of language: the ability to guide a reader’s or listener’s attention exactly where it needs to go, creating cohesion and clarity one reference at a time.

This is the bit that actually matters in practice.
Putting It Into Practice: A Quick Diagnostic
To solidify the distinction between these as a determiner and a pronoun, try this simple substitution test when editing your own work. If you can replace these with these [specific noun] without changing the meaning, it is functioning as a determiner. If the sentence collapses or requires a noun to be inserted after it, these is acting as a pronoun standing alone.
- Test 1: These cookies are stale. → These [cookies] are stale. (Determiner)
- Test 2: These are stale. → These [cookies] are stale. (Pronoun—noun is implied/recovered from context)
This diagnostic works equally well for distinguishing these from those. If the referent is physically or psychologically near, these is appropriate; if distant, those takes its place. In real terms, errors often arise not from confusion about number—both are strictly plural—but from a mismatch in perceived proximity. A writer describing a past event might incorrectly write, "These were the days" when reflecting on a remote childhood; "Those were the days" correctly signals the temporal distance.
Final Thought
Language is an architecture of reference. Mastering these is not merely a matter of memorizing a part-of-speech label; it is an exercise in spatial and cognitive precision. Day to day, every demonstrative—this, that, these, those—acts as a structural beam, connecting the abstract world of ideas to the concrete reality shared between speaker and listener. Now, when you write these, you are inviting your audience to look here, now, at these specific things. Used with intention, that invitation is one of the most powerful tools in the writer’s kit.
