Definition of “Which” and Its Function

The word “which” is primarily used as a relative pronoun. A relative pronoun connects a relative clause to a main clause. In simpler terms, it introduces a clause that gives extra information about a noun or pronoun mentioned earlier in the sentence. This added information can be essential to understanding the sentence or simply provide additional details.

For example, in the sentence “The book, which I borrowed from the library, is very interesting,” the clause “which I borrowed from the library” is a relative clause introduced by “which.” This clause provides extra information about the noun “book.” Relative clauses can be either restrictive (essential to the meaning of the sentence) or nonrestrictive (providing additional but non-essential information, usually set off by commas).

Understanding the function of “which” is the first step towards appreciating the nuances of its alternatives. Recognizing when and how “which” is used will help you identify situations where other words or phrases might be more appropriate or add stylistic flair to your writing.

Structural Breakdown of Relative Clauses

Relative clauses are dependent clauses that modify nouns or pronouns. They typically begin with a relative pronoun (such as “which,” “that,” “who,” “whose,” “whom”) or a relative adverb (such as “where,” “when,” “why”). The structure of a relative clause generally follows this pattern: Relative Pronoun/Adverb + Subject + Verb (+ Object/Complement). However, the subject may be omitted in certain types of reduced relative clauses (discussed later).

Consider the sentence: “The car that I bought is red.” Here, “that” is the relative pronoun, “I” is the subject, and “bought” is the verb. The entire clause “that I bought” modifies the noun “car.” Understanding this basic structure allows you to deconstruct and analyze complex sentences, making it easier to identify and use appropriate alternatives to “which.” The position of a relative clause is also important; it usually follows directly after the noun it modifies.

There are also different types of relative clauses: defining (restrictive) and non-defining (non-restrictive). Defining relative clauses are essential to the meaning of the sentence and are not set off by commas. Non-defining relative clauses provide extra information and are always set off by commas. The choice between “that” and “which” often depends on whether the clause is defining or non-defining.

Alternatives to “Which”

While “which” is a versatile relative pronoun, several alternatives can provide greater precision or stylistic variation. These alternatives include “that,” “who,” “whose,” “where,” “when,” “in which,” and in some specific cases, “what.” Each alternative has its own specific usage rules and contexts where it is most appropriate.

“That”

“That” is a relative pronoun that can often be used interchangeably with “which,” especially in defining (restrictive) relative clauses. A defining relative clause provides essential information that identifies the noun it modifies. However, “that” is generally preferred over “which” in defining relative clauses because it sounds more natural. For example, instead of saying “The book which I needed was out of stock,” it is more common to say “The book that I needed was out of stock.”

Key takeaway: “That” is typically used in defining relative clauses and is often the preferred choice for these clauses. It is generally not used in non-defining relative clauses, which require “which.”

“Who”

“Who” is used as a relative pronoun to refer to people. It replaces “which” when the relative clause is providing information about a person or group of people. For example, instead of saying “The student which won the award is here,” you would say “The student who won the award is here.” “Who” can be used in both defining and non-defining relative clauses, although “that” can sometimes be used in defining relative clauses about people as well.

Key takeaway: Use “who” when the relative clause refers to a person or people. It’s a more specific and accurate pronoun in these contexts.

“Whose”

“Whose” is a relative pronoun that indicates possession. It replaces “which” when the relative clause is showing that something belongs to someone or something. For example, instead of awkwardly saying “The company which its profits increased is expanding,” you can say “The company whose profits increased is expanding.” “Whose” can refer to both people and things, making it a versatile option for showing possession.

Key takeaway: Use “whose” to show possession or ownership within a relative clause. It adds clarity and conciseness to sentences.

“Where”

“Where” is a relative adverb that is used to refer to places. It replaces “which” when the relative clause is providing information about a location. For example, instead of saying “The city which I was born in is very large,” you can say “The city where I was born is very large.” “Where” simplifies the sentence and makes it more direct. Note that you often need to restructure the sentence slightly when using “where.”

Key takeaway: Use “where” to indicate a place or location within a relative clause. It avoids awkward phrasing and improves sentence flow.

“When”

“When” is a relative adverb used to refer to times or occasions. It replaces “which” when the relative clause is providing information about a specific time. For example, instead of saying “The day which the event took place on was a Tuesday,” you can say “The day when the event took place was a Tuesday.” Similar to “where,” using “when” typically requires some sentence restructuring for clarity.

Key takeaway: Use “when” to specify a time or occasion within a relative clause. It provides a clear and concise way to indicate temporal relationships.

“In Which”

“In which” is a phrase that can often replace “where” when referring to places, but it is more formal. It’s particularly useful when the preposition “in” is essential to the meaning of the sentence. For example, instead of saying “The box where I keep my letters is old,” you could say “The box in which I keep my letters is old.” While “where” is generally more common, “in which” can add a touch of formality or precision.

Key takeaway: Use “in which” as a more formal alternative to “where,” especially when the preposition “in” is integral to the clause’s meaning.

“What”

“What” is a relative pronoun that can sometimes replace “which” in specific contexts, particularly when referring to a general idea or concept rather than a specific noun. For example, instead of saying “I heard the thing which he said,” you can say “I heard what he said.” “What” effectively combines the antecedent and the relative pronoun into a single word. This usage is often seen in clauses that function as the subject or object of a sentence.

Key takeaway: Use “what” to refer to a general idea or concept, combining the antecedent and relative pronoun for a more concise expression.

Usage Rules and Guidelines

To effectively use alternatives to “which,” it’s essential to understand the specific rules and guidelines associated with each option. These rules often depend on the type of clause (restrictive or nonrestrictive) and the context of the sentence.

Restrictive vs. Nonrestrictive Clauses

Restrictive (Defining) Clauses: These clauses are essential to the meaning of the sentence. They provide information that is necessary to identify the noun being modified. Restrictive clauses are not set off by commas. In restrictive clauses, “that” is often preferred over “which.”

Nonrestrictive (Non-defining) Clauses: These clauses provide additional information that is not essential to the meaning of the sentence. They are set off by commas. In nonrestrictive clauses, “which” is used, and “that” is not allowed.

Prepositions in Relative Clauses

Prepositions can sometimes cause confusion in relative clauses. Generally, prepositions can either precede the relative pronoun or appear at the end of the clause. However, the placement of the preposition can affect the formality and clarity of the sentence.

Preposition at the end of the clause (Informal): This is more common in spoken English and informal writing.

Preposition before the relative pronoun (Formal): This is more common in formal writing. When the preposition precedes the relative pronoun, use “which” or “whom” (for people) instead of “that.”

Common Mistakes to Avoid

Using alternatives to “which” can sometimes lead to errors. Here are some common mistakes to watch out for:

1. Using “that” in nonrestrictive clauses: This is a very common error. Remember, “that” should only be used in restrictive clauses.

Incorrect: The book, that I borrowed from the library, is very interesting.

Correct: The book, which I borrowed from the library, is very interesting.

2. Using “which” to refer to people: Unless you’re referring to a group or category in an abstract sense, use “who” or “whom” for people.

Incorrect: The student which won the award is here.

Correct: The student who won the award is here.

3. Misplacing prepositions: While it’s acceptable to end a clause with a preposition in informal writing, be mindful of clarity. In formal writing, place the preposition before “which” or “whom.”

Awkward: The project that I am working on it is due soon.

Correct: The project on which I am working is due soon.

Correct: The project that I am working on is due soon.

4. Incorrect use of “whose”: “Whose” indicates possession. Make sure it logically connects the noun it modifies to the possessor.

Incorrect: The company which is owned by him is successful. (Could be better)

Correct: The company whose owner is him is successful.

Correct: The company whose owner is him is successful.

5. Forgetting commas with nonrestrictive clauses: Commas are essential for indicating that a clause is nonrestrictive.

Incorrect: My car which is old needs repairs.

Correct: My car, which is old, needs repairs.

Practice Exercises

Test your understanding with these practice exercises. Fill in the blanks with the appropriate relative pronoun or adverb (“that,” “who,” “whose,” “where,” “when,” “in which,” or “what”).

Advanced Topics: Reduced Relative Clauses

In some cases, relative clauses can be reduced to shorter phrases, making sentences more concise. This usually involves omitting the relative pronoun and auxiliary verb.

Reducing with Present Participles: When the relative clause contains an active verb, you can often reduce it by using the present participle (-ing form) of the verb.

Reducing with Past Participles: When the relative clause contains a passive verb, you can often reduce it by using the past participle of the verb.

Reducing with To-Infinitive Phrases: When the relative clause expresses purpose or necessity, you can often reduce it by using a to-infinitive phrase.

Frequently Asked Questions

Conclusion

Mastering the alternatives to “which” is a valuable skill that can significantly enhance the clarity, precision, and style of your writing and speaking.
