Key Takeaways<\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n A relative pronoun is a connector. <\/p>\n\n\n\n Its job is to hook one part of a sentence to another by referring back to a noun that\u2019s already been mentioned. <\/p>\n\n\n\n It relates<\/em> extra information to a person, place, thing, or idea without starting a brand new sentence<\/p>\n\n\n\n It sits at the start of something called a relative clause, which is just a fancy name for a part of a sentence that describes or gives more information about a noun.<\/p>\n\n\n\n So, rather than stacking up short, choppy sentences, relative pronouns let you form more layered sentences.<\/p>\n\n\n\n Historically, relative pronouns have been around for centuries, but Old English didn\u2019t use them<\/a> the way we do now. <\/p>\n\n\n\n Back then, people relied more on word order and repetition. <\/p>\n\n\n\n As English absorbed Latin and French influences, the language got more complex, and the grammar had to keep up. <\/p>\n\n\n\n Relative pronouns grew out of that shift, where they offered a way to express subtler relationships between ideas.<\/p>\n\n\n\n If you\u2019re going to understand what’s a relative pronoun, you need to know which ones you will commonly come across. <\/p>\n\n\n\n Here\u2019s a list of the most common relative pronouns: <\/p>\n\n\n\n In addition, \u2018when, where, why\u2019 aren\u2019t technically on the classic relative pronoun list, but they play the same game. <\/p>\n\n\n\n When<\/em><\/strong> connects to time, where<\/em><\/strong> to place, why<\/em><\/strong> to reason. <\/p>\n\n\n\n And if you’re putting together a school assignment while trying to wrap your head around which pronoun goes where, check out Undetectable Ask AI<\/a>.<\/p>\n\n\n\n It gives you fast, clear answers to your confusion around the use of relative pronouns without making you dig through pages of dry grammar explanations. <\/p>\n\n\n\n You can also copy-paste your own writing and get instant feedback on your sentence structure.<\/p>\n\n\n Now that you know what relative pronouns are and how they help connect extra information to nouns, let’s try to understand how they are used in sentences.<\/p>\n\n\n\n You will see them in two ways: the defining clause and the non-defining clause. <\/p>\n\n\n Defining clauses lock down which person or thing you\u2019re talking about. They\u2019re called \u201crestrictive\u201d because they restrict or narrow the meaning of the noun.<\/p>\n\n\n\n Take this sentence, for example:<\/p>\n\n\n\n \u201cThe student who failed the test needs to retake it.\u201d<\/em><\/p>\n\n\n\n Here, the clause \u201cwho failed the test\u201d tells us which student we\u2019re talking about. There may be 30 students, but you\u2019re not talking about all of them, just the one who bombed the test.<\/p>\n\n\n\n Also, in defining clauses, we often use “that” instead of “which” when talking about things. It\u2019s cleaner and more accepted in formal writing.<\/p>\n\n\n\n Non-defining clauses are the little asides you could technically remove without breaking the sentence. The sentence still makes sense without them. You’re just tossing in a bit of extra info when you use them.<\/p>\n\n\n\n For example, \u201cMy aunt, who lives in Italy, makes the best lasagna.\u201d Or, \u201cMy uncle, who used to be a pilot, now runs a coffee shop.\u201d<\/p>\n\n\n\n In both of these sentences, the clause between the commas isn’t really necessary for the sentence to make sense. Instead, it just adds more meaning and context.<\/p>\n\n\n\n Non-defining clauses only use who, whom, whose, and which as relative pronouns. You do not use ‘that’, in particular. <\/p>\n\n\n\n The only difference between defining and non-defining clauses, grammatically speaking, is the presence of commas. <\/p>\n\n\n\n That little change can completely flip what the sentence is saying.<\/p>\n\n\n\n Let\u2019s compare two almost identical sentences:<\/p>\n\n\n\n This sentence only talks about the latecomers. It implies that some guests were on time, and some were not. Only the ones who strolled in late were punished with an empty plate.<\/p>\n\n\n\n We added commas, and now it sounds like all the guests were late and everyone missed dinner. <\/p>\n\n\n\n The clause \u201cwho arrived late\u201d is no longer narrowing down which guests you’re referring to, it’s just throwing in extra info about all the guests.<\/p>\n\n\n\n A complex sentence<\/a> is just a sentence that combines an independent clause (a complete thought that can stand alone) with one or more dependent clauses (incomplete thoughts that need backup).<\/p>\n\n\n\n The dependent clauses usually start with words like “because,” “although,” “if,” “or,” or, you guessed it, relative pronouns.<\/p>\n\n\n\n Relative pronouns introduce relative clauses, which are a kind of dependent clause. <\/p>\n\n\n\n That means any sentence using them is, by nature, a complex sentence.<\/p>\n\n\n\n Let’s look at an example.<\/p>\n\n\n\n \u201cThe professor who gave the guest lecture on quantum computing last night has published a book.”<\/em><\/p>\n\n\n\n If I break it down, then:<\/p>\n\n\n\n Similarly, here’s an example of a non-living thing.<\/p>\n\n\n\n \u201cI finally replaced the old coffee machine, which had been leaking mysteriously and short-circuiting the kitchen outlet every other week.\u201d<\/em><\/p>\n\n\n\n Relative pronouns are often confused with demonstrative and interrogative pronouns. <\/p>\n\n\n\n Here\u2019s how to differentiate between them. <\/p>\n\n\n\n We’ve discussed in great detail how relative pronouns are connectors, and grammatically, they introduce dependent (subordinate) clauses that describe or define a noun mentioned earlier.<\/p>\n\n\n\n Demonstrative pronouns don\u2019t connect clauses. <\/p>\n\n\n\n They stand in place of nouns and point to something specific, either in physical space or in context. <\/p>\n\n\n\n You will usually see them as part of simple sentence structures and as the subject or object of the sentence. <\/p>\n\n\n\n For instance:<\/p>\n\n\n\n \u201cThat was the most powerful documentary I\u2019ve seen on climate change in years.\u201d<\/em><\/p>\n\n\n\n The pronoun ‘that’ doesn\u2019t introduce a clause here. It stands on its own and refers to something already known, probably the documentary that the speaker and listener both just watched or talked about.<\/p>\n\n\n\n In short: <\/p>\n\n\n\n The difference between relative and interrogative pronouns often trips people up because many pronouns, e.g., who, whom, which, and what, all appear in both categories. <\/p>\n\n\n\n But again, the difference lies in what they do in a sentence.<\/p>\n\n\n\n Relative pronouns, like before, introduce dependent clauses that describe a noun.<\/p>\n\n\n\n Interrogative pronouns, on the other hand, are used to ask questions. <\/p>\n\n\n\n They stand in for the noun you\u2019re asking about and open a sentence, not follow a noun like relative pronouns do.<\/p>\n\n\n\n For example, \u201cWho stayed with the patient overnight in the ICU?\u201d<\/em><\/p>\n\n\n\n The interrogative pronoun ‘who’ is the subject of a question.<\/p>\n\n\n\n Again, to summarize:<\/p>\n\n\n\n Let\u2019s put the different types of pronouns discussed here all in one place so you can actually compare without flipping through grammar books.<\/p>\n\n\n\n To really sharpen your instinct for which pronoun to use where, I really recommend using Undetectable AI Chat<\/a>. <\/p>\n\n\n You can actually run drills specifically on relative clauses or pronoun choice and get detailed feedback.<\/p>\n\n\n\n It\u2019s way more effective than scrolling through passive worksheets because you\u2019ll get a feel for how these pronouns actually function in live language. <\/p>\n\n\n\n Experience the power of our AI Detector and Humanizer in the widget below!<\/p>\n\n\n\n\n
