Important Differences Between That and Which
Feature | “That” | “Which” |
Type | Pronoun, determiner, adverb, conjunction | Pronoun, relative pronoun, determiner |
Restrictiveness | Restrictive, provides essential information | Non-restrictive, provides additional, non-essential info |
Usage | Used with both singular and plural nouns | Used with things, objects, and sometimes animals |
Introduction | Introduces relative clauses that are necessary for clarity | Introduces relative clauses that add extra information |
Punctuation | No comma required when introducing essential information | Requires a comma when introducing non-essential info |
Interchangeability | Less interchangeable, often preferred for essential info | More interchangeable, especially in informal contexts |
Key Differences Between That and Which
Here are some key differences between “that” and “which”:
- Position in a Sentence: “That” is often used in restrictive clauses that are essential to the meaning of the sentence and are usually positioned immediately after the noun they modify. “Which,” on the other hand, is commonly used in non-restrictive clauses that provide additional information and are set off by commas.
- Restrictive clause with “that“: The car that I bought is red. (The clause “that I bought” is essential to identify the specific car.)
- Non-restrictive clause with “which“: The car, which is red, is mine. (The clause “which is red” provides additional information but is not necessary to identify the car.)
- Informality: “That” is generally considered more informal than “which” when used as a relative pronoun. In formal writing, “which” is often preferred for non-restrictive clauses.
- Antecedent: “That” is used to refer to both people and things, whereas “which” is typically used to refer to things, objects, and sometimes animals.
- “That”: The book that I’m reading is interesting. (Referring to a thing)
- “Which”: The dog which is barking is mine. (Referring to an animal)
- Interchangeability: In some cases, “that” and “which” can be interchangeable, especially in informal contexts. However, when strict clarity and adherence to formal writing conventions are required, it is advisable to use “that” for restrictive clauses and “which” for non-restrictive clauses.

Conclusion Between That and Which
In conclusion, “that” and “which” are both pronouns used to introduce relative clauses in English.

In terms of interchangeability, “that” is less interchangeable and is often preferred for essential information, while “which” is more interchangeable, especially in informal contexts.
