Demonstratives are small words with a big job: they point to specific people, objects, ideas, and situations, helping English speakers show distance, number, and focus with precision. In this hub on demonstratives practice, we will cover the four core forms—this, that, these, and those—then move into a quick quiz, the most common errors, and the wider “miscellaneous” issues that learners regularly meet in grammar study. A demonstrative adjective comes before a noun, as in “this book” or “those shoes,” while a demonstrative pronoun stands alone, as in “this is useful” or “those were expensive.” The choice depends on two basic contrasts: singular versus plural, and near versus far. “This” and “these” usually refer to things close in place, time, or attention; “that” and “those” usually refer to things farther away. In real teaching and editing work, I have found that learners often know the basic chart but still hesitate when conversation becomes fast, when reference is abstract, or when another pronoun seems possible. That hesitation matters because demonstratives appear constantly in speech, academic writing, customer emails, classroom instructions, and exams. If you want clearer grammar, better sentence flow, and fewer avoidable mistakes, mastering demonstratives is one of the fastest wins in English.
What demonstratives do in real sentences
Demonstratives identify exactly what the speaker means. In “this pen is mine,” “this” narrows the reference to one nearby pen. In “those deadlines were unrealistic,” “those” points to several deadlines already known to the listener. The grammar rule is simple: use “this” for singular near items, “that” for singular far items, “these” for plural near items, and “those” for plural far items. Near and far are not only physical. You can say “this week” because the time period is current, but “that year” because it is more distant in memory. You can say “listen to this” before introducing an idea you are about to say, and “that was a good point” after someone else has finished speaking.
Demonstratives work as determiners and pronouns. As determiners, they come before nouns: “these examples,” “that mistake.” As pronouns, they replace nouns: “these are helpful,” “that belongs in the second paragraph.” This distinction matters because many learner errors happen when the noun is omitted or when agreement breaks down. For example, “this books are heavy” is wrong because singular “this” cannot modify plural “books.” The correct form is “these books are heavy.” In professional writing, agreement errors with demonstratives weaken credibility immediately because they are so visible and so basic.
How to choose this, that, these, or those
The fastest method is to ask two questions. First, is the noun singular or plural? Second, is the referent near or far in context? If it is singular and near, use “this.” If it is singular and far, use “that.” If it is plural and near, use “these.” If it is plural and far, use “those.” I teach learners to test the sentence by imagining the speaker pointing. “This answer” suggests the answer on the paper in front of you; “that answer” suggests one farther away, perhaps on another page or from an earlier discussion. “These problems” suggests the problems now under review; “those problems” often refers to different or more distant ones.
Context defines distance. In meetings, “this issue” often means the topic currently on the agenda, while “that issue” refers to a different issue raised earlier. In essays, “this argument” usually points forward to the argument now being developed, while “that argument” often refers backward to another writer’s claim. In conversation, tone can add meaning. “I like this” can sound engaged and immediate. “I like that” can signal appreciation after seeing or hearing something completed. The forms are grammatical markers, but they also shape emphasis, coherence, and reader guidance.
Quick quiz: check your demonstratives
Use this short quiz to test understanding. Choose the correct demonstrative in each sentence. 1) ___ chair beside me is broken. 2) ___ mountains in the distance look snowy. 3) Can you hand me ___ files on my desk? 4) I did not enjoy ___ movie we watched last night. 5) ___ is exactly what I wanted to hear. The correct answers are: 1) this, because the chair is singular and near; 2) those, because mountains are plural and far; 3) these, because files are plural and near; 4) that, because the movie is singular and more distant in time; 5) this, because the speaker is focusing on a present statement or idea.
| Form | Number | Usual distance | Example |
|---|---|---|---|
| This | Singular | Near | This lesson is short. |
| That | Singular | Far | That building is old. |
| These | Plural | Near | These questions are easy. |
| Those | Plural | Far | Those lights are bright. |
If you missed any item, look at whether the problem was number or distance. In classroom settings, number causes more mistakes at beginner levels, while abstract distance causes more mistakes at intermediate and advanced levels. A useful correction technique is substitution: replace the noun with “it” or “they” first, then rebuild the sentence. If the referent is “it” and near, choose “this”; if it is “they” and far, choose “those.” This quick diagnostic works well in self-study and editing.
Common errors learners make
The first common error is number mismatch. Sentences like “that books are new” and “these car is fast” are wrong because demonstratives must agree with the noun. The second error is unclear reference. In a paragraph with several ideas, a sentence such as “this shows a problem” may confuse the reader if “this” could refer to several previous statements. Strong writers often replace vague demonstratives with a summary noun: “this trend,” “this policy change,” or “that assumption.” This small edit improves clarity immediately.
The third error is overusing “this” in formal writing. Because “this” feels easy, learners sometimes start many consecutive sentences with it: “This is important. This is because costs rose. This created delays.” The grammar is not wrong, but the style becomes repetitive and weak. A better version varies structure: “The increase in costs was important because it created delays.” The fourth error is using demonstratives where the definite article is more natural. For example, “I went to that store near my house” may sound odd if there is no contrast or pointing intention; “the store near my house” is often better.
Another frequent problem appears in spoken English when learners use “that” for emotional distance without realizing the effect. Saying “that idea of yours” can sound colder or more critical than “this idea” in the same conversation. Native speakers often use demonstratives strategically to include or distance themselves from an idea. This nuance matters in customer service, team leadership, and teaching, where tone affects cooperation. Finally, many learners confuse demonstratives with subject pronouns in reduced or fast speech. “These are” may be heard but written as “this are.” Careful proofreading catches this.
Miscellaneous grammar issues connected to demonstratives
As a hub under Grammar, this page should connect demonstratives to related “miscellaneous” topics that students often study together. One is demonstratives with one and ones: “this one is cheaper,” “those ones are damaged.” In careful style, “those are damaged” is often cleaner than “those ones are damaged,” but both appear in speech. Another linked topic is demonstratives in introductions and presentations: “This is Maria from finance” introduces a person near the speaker or currently being presented, while “That was Maria’s report” refers back to something completed. Reported speech also overlaps: “That was not what I meant” points back to an earlier statement.
There is also an important difference between demonstratives and articles. “A report” introduces any report, “the report” identifies a known report, and “this report” identifies a known report with added focus or immediacy. In editing business documents, I often see writers choose “this” when they really mean “the.” Overusing demonstratives can make prose sound pushy or cluttered. Another related issue is sentence cohesion. Academic style guides such as the Chicago Manual of Style and many university writing centers warn against bare “this” in argumentative prose. Instead of “this proves the point,” write “this result proves the point” or “this discrepancy proves the point.” The noun after the demonstrative anchors meaning and helps readers follow the logic.
Practice strategies that actually improve accuracy
The best practice for demonstratives is contrastive practice, not isolated memorization. Put near and far, singular and plural, side by side: “this email/these emails/that email/those emails.” Then move from objects to time and ideas: “this morning,” “that night,” “these concerns,” “those assumptions.” I have seen the fastest improvement when learners practice with their real environment. Label items on a desk, describe photos, or retell a meeting: “this notebook,” “those chairs,” “that comment from yesterday,” “these edits in the current draft.” Real context makes the near-far distinction intuitive.
A second effective method is paragraph revision. Take a short paragraph and circle every “this,” “that,” “these,” and “those.” Check agreement, then ask whether the reference is clear without guessing. If not, add a noun. Digital tools can help with proofreading, but they should not replace judgment. Grammarly and Microsoft Editor may catch agreement problems, yet they often miss vague reference because the sentence is technically grammatical. The most reliable test is reader comprehension: can someone identify the exact referent instantly? If yes, your demonstrative is working. If not, revise. For lasting improvement, keep a short error log and rewrite your own incorrect sentences until the choices become automatic.
Demonstratives are foundational because they connect grammar to meaning in every kind of English, from casual conversation to formal analysis. The core system is straightforward: this and these point to what is near, that and those point to what is farther away; singular forms match singular nouns, and plural forms match plural nouns. The challenge is not memorizing the chart but applying it clearly when the reference is abstract, when tone matters, or when writing requires precision. The quick quiz and examples above show the patterns that matter most, and the common errors reveal where learners usually lose accuracy: agreement mistakes, vague reference, repetitive style, and overuse in place of articles. If you treat demonstratives as tools for guiding attention rather than just four vocabulary items, your grammar improves quickly. Review your own sentences, replace unclear references with specific nouns, and practice with real examples from daily life. Then continue through the rest of this Grammar hub to build stronger control over the miscellaneous points that make English sound natural, accurate, and confident.
Frequently Asked Questions
1. What is the difference between this, that, these, and those?
The four demonstratives in English show two things at once: number and distance. This and that are singular. These and those are plural. In terms of distance, this and these usually refer to something near the speaker, while that and those usually refer to something farther away. For example, you would say this pen if the pen is in your hand, but that pen if it is across the room. Likewise, these shoes refers to more than one shoe near you, while those shoes points to shoes farther away.
Demonstratives can also be used in less physical ways. Distance is not always about space. It can also show emotional or conversational distance. For example, a speaker may say this idea to present something as immediate, relevant, or important, but that idea to sound more detached. The same pattern appears in time: this week usually means the current week, while that day refers to a more distant point in the past or in a story. Understanding this basic system makes demonstratives much easier to use accurately in both speaking and writing.
2. What is a demonstrative adjective, and how is it different from a demonstrative pronoun?
A demonstrative adjective comes before a noun and identifies exactly which person, thing, or idea you mean. In sentences such as this book is helpful, that teacher is strict, these exercises are easy, and those answers are correct, the words this, that, these, and those are functioning as adjectives because they directly modify a noun. They help narrow meaning and point the listener or reader to a specific item rather than something general.
A demonstrative pronoun, by contrast, replaces the noun instead of coming before it. For example, in this is helpful or those are correct, the demonstratives stand alone and act as pronouns. The choice between adjective and pronoun depends on whether the noun is stated. If the noun follows, the demonstrative is acting adjectivally. If the noun is omitted because the meaning is already clear from context, the demonstrative works as a pronoun. This distinction is especially useful in grammar exercises and quizzes, because many learners know the forms but are less confident about the role each form plays in the sentence.
3. What are the most common mistakes learners make with demonstratives?
The most common error is mismatching singular and plural nouns. For instance, learners may say this books or those car, but these are incorrect because the demonstrative and the noun must agree in number. The correct forms are this book, that car, these books, and those cars. Another frequent problem is choosing the wrong distance word, such as using this for something clearly far away or those for objects that are physically close. While conversation sometimes allows flexibility, basic grammar practice should follow the standard near-versus-far pattern.
Learners also often confuse demonstratives with articles or other determiners. For example, they may write this a book or those my friends. In standard English, demonstratives usually do not combine freely with articles like a or an in front of the same noun. Another issue appears in speaking and writing when the noun is unclear. If someone says I do not like that, the listener may not know what that refers to unless the context is obvious. In formal writing, precise reference matters. A good rule is to use demonstratives carefully, make sure they match the noun in number, and ensure the reader can immediately identify what is being pointed to.
4. How can I practice demonstratives effectively with a quick quiz?
The best quick quizzes focus on patterns rather than isolated memorization. Start with simple sentence completion: ___ apple in my hand is fresh, ___ houses across the street are old, and similar examples. This kind of exercise trains you to notice both number and distance at the same time. You can then move to error correction, where you identify and fix mistakes such as that pencils or these chair. These short drills are highly effective because they build accuracy fast and make common problems visible.
To get better results, mix visual, spoken, and written practice. If you are studying alone, point to real objects around you and describe them aloud: this phone, that window, these notes, those buildings. If you are using a worksheet or online quiz, say the answers out loud before writing them. That helps connect grammar with natural speech. After each quiz, review every wrong answer and ask why it was wrong. Was the noun singular or plural? Was the object near or far? Did the sentence need an adjective before a noun, or a pronoun standing alone? That kind of review is where real learning happens, because it turns a quick quiz into long-term improvement.
5. Are there any tricky or miscellaneous uses of demonstratives that learners should know?
Yes. Demonstratives are simple at first, but they appear in several wider grammar situations that can be confusing. One important area is time reference. English speakers say this morning, this year, and these days for time periods that feel current or connected to the present. By contrast, that night or those years can refer to a more distant time, often in storytelling or reflection. Another tricky area is discourse reference, where a demonstrative points not to a physical object but to an idea, statement, or event. For example, after hearing an explanation, someone might say That makes sense. Here, that refers to the previous idea, not to a visible object.
There are also style and clarity issues. In conversation, demonstratives are very common and natural because speakers can use gesture, tone, and shared context. In writing, however, vague demonstratives can weaken clarity. A sentence such as This shows the problem may be too unclear if the reader cannot tell what this refers to. Many strong writers solve this by adding a clear noun phrase, such as This mistake shows the problem or That argument misses the main point. Learners should also notice that demonstratives can signal attitude. This wonderful book feels immediate and engaged, while that book can sound more neutral, distant, or even critical depending on context. So although demonstratives are short words, mastering them improves grammar, precision, and overall communication.
