In Part I of this essay, we discussed the difference between the two kinds of relative clauses: a defining or restrictive relative clause provides essential information to the main clause of a sentence, while a nondefining or nonrestrictive relative clause provides information not essential to the idea or context of the main clause. We then saw that when the antecedent noun is a person, a defining relative clause is inseparably linked to the main clause by the relative pronoun “who,” as in “Young people who spend too much time playing computer games tend to have very short attention spans.” A nondefining relative clause is similarly introduced by the relative pronoun “who,” but it must always be set apart from the main clause by a pair of commas, as in “The great Jose Rizal, who has been called ‘The Pride of the Malay Race,’ was actually of Chinese ancestry.” Those commas indicate that the main clause can stand even without the relative clause.

(Again, to get a surer feel of the difference between a defining clause and a nondefining clause, see what happens when we drop the relative clauses from each of the examples above: “Young people […] tend to have very short attention spans.” “The great Jose Rizal […] was actually of Chinese ancestry.” With the relative clause gone in the first sentence, the statement has become too overgeneralized to be true; in contrast, even without the relative clause, the second statement remains perfectly valid.)

So far, though, we have only discussed the use of relative pronouns when persons are the antecedent subjects. When the subject is an animal, a place, an inanimate object, or a concept, we can no longer use the relative pronoun “who” to link the relative clause to its antecedent subject. Instead, we use either the relative pronouns “that” or “which” depending on the kind of relative clause we are using in the sentence.

In American English specifically, we use “that” to link a defining or restrictive clause to a nonhuman antecedent subject, as in the following examples: “The Siamese cat that our father found on a street gutter a year ago became the family’s favorite pet.” “The treehouse that the Sanchez brothers built during their teens was gone.” “The great idea that was propounded by the neophyte legislator got mangled due to too much politicking.” In these sentences, the relative clause is crucial to understanding the idea or context of the main clause; dropping the relative clause can seriously alter the import of—or significantly detract from—the intended meaning: “The Siamese cat became the family’s favorite pet.” “The treehouse […] was gone.” “The great idea […] got mangled due to too much politicking.”

On the other hand, we use the relative pronoun “which” to link a nondefining or nonrestrictive clause to a nonhuman antecedent subject, as in the following examples: “The Decline and Fall of the Roman Empire, which was written by the British historian Edward Gibbon in the 18th century, has been hailed as one the greatest historical works produced by Western man.” “A subspecies of the chevrotain, which is also known as the mouse deer, is indigenous to Palawan and nearby islands.” The pair of enclosing commas is mandatory in such constructions; it sets the relative clause apart from the main clause and indicates that the relative clause is not essential to the idea of the main clause.

Indeed, when the relative clauses are dropped from such sentences, we will find that the main clauses can very well stand by themselves: “The Decline and Fall of the Roman Empire […] has been hailed as one the greatest historical works produced by Western man.” “A subspecies of the chevrotain […] is indigenous to Palawan and nearby islands.” (September 27, 2011)

Next week, in Part III of this essay, we will discuss how the American English usage of the relative clauses differs from that of British English and how we can streamline sentence constructions that use relative clauses.

One of the most common mistakes I encounter in my work as copyeditor and grammar consultant is the misuse of the relative pronouns. Not a few of the manuscripts I edit often embarrassingly fumble or stumble when using “who,” “which,” or “that” to relate a qualifying clause to an antecedent noun in the sentence. And I must admit that early in my writing career, I used to get pretty mixed up with the relative pronouns myself. Simply on gut feel, I would indiscriminately use “which” and “that” to announce my relative clauses, so I can imagine that my grammar then was probably correct no more than 50 percent of the time.

I can see now that I got into this predicament largely because in my youth, I read a lot of novels by British authors. It’s not that I didn’t enjoy them or profit from them in terms of getting a better grasp of the English language, but as I was to find out to my consternation many years later, British English uses “which” and “that” in practically the opposite way American English does.

So, I think it’s high time we did a full-dress review once more of the relative pronouns. We’ll do it specifically in the American English standard, which is the standard we are using in the Philippines.

The relative pronouns are, of course, “who,” “which,” “that,” “whom,” “whoever,” “whomever,” “whatever,” and “whichever.” Each of them serves to relate a dependent or subordinate clause to an antecedent noun in a sentence, which can either be the subject or object of that dependent clause. And taken together, the relative pronoun and the dependent clause it introduces constitute what is called a relative clause.

Let’s examine this sentence that has a relative clause attached to it: “People who complain loudest about a problem often don’t do anything to solve it.” Here, the relative clause is “who complain loudest about a problem” and “who” is the relative pronoun that relates it to the antecedent noun “people,” which is the subject of the sentence. What the relative clause does here is to specify the particular people being written about; functionally, it provides additional information about the antecedent noun so the reader can understand the context of the statement better.

Now, in English, the choice of relative pronoun depends on two things: (1) whether the additional information being given is essential or not essential to the understanding of the idea or context of the main clause; and (2) whether the antecedent noun is a person or an animal or inanimate object. Either way, however, the relative pronoun can function as a subject or an object or can take its possessive form.

At any rate, a relative clause that provides essential information to the main clause is what is known as a defining or restrictive relative clause, as in the example we looked at earlier: “People who complain loudest about a problem often don’t do anything to solve it.” Here, the relative clause “who complain loudest about a problem” can’t be taken out from the sentence, for to do so will seriously change the meaning of what’s being said. Indeed, if we drop that relative clause, we would end up with “People don’t do anything to solve [a problem]”—a sentence that unreasonably and illogically generalizes on human behavior.

On the other hand, when the information in the relative clause is not essential to the idea or context of the main clause, we have what is called a nondefining or nonrestrictive relative clause. In such cases, a comma is normally needed to separate the relative clause from the main clause, as in this sentence: “The company decided to fire its legal counsel, who bungled the court filings in a crucial corporate dispute.” Here, the main clause can stand even without the relative clause.

We’ll continue this discussion in next week’s edition of the Forum.
