A writer edits 'The report which I submitted last week was approved' to 'The report that I submitted last week was approved.' What is the semantic significance of this change?
ANone — 'that' and 'which' are interchangeable in standard modern usage
BThe 'that' version signals the clause is essential for identifying which report is meant; the 'which' version (properly set off by commas) would signal supplementary information about an already-identified report
C'That' is more formal than 'which' and is appropriate for professional writing; the meaning is identical
D'Which' is reserved for questions, so the 'that' version is simply more grammatical in a statement
The choice between 'that' and 'which' encodes whether the clause is restrictive or non-restrictive. 'The report that I submitted last week' uses a restrictive clause — essential for identifying which report among possibly many. A non-restrictive version would be 'The report, which I submitted last week, was approved' — the commas signal the clause is supplementary bonus information about a report already fully identified. The two are not stylistic variants; they make different claims about what information is essential.
Question 2 Multiple Choice
A student argues: 'I can use which wherever I want — it sounds more sophisticated than that.' What specific grammatical and semantic problem does this create?
ANo real problem — major style guides disagree on this distinction, so both choices are defensible
BUsing 'which' without commas where 'that' belongs makes a restrictive clause appear non-restrictive, potentially misleading readers about which noun is being identified
C'Which' can only be used in interrogative sentences, not in relative clauses, making the sentence ungrammatical
DThe only problem is stylistic — it sounds informal and imprecise but doesn't change meaning
The commas matter as much as the pronoun choice. If you write 'The car which I rented was damaged' (no commas), you are using 'which' in a restrictive context — signaling essential identification — which is the role of 'that.' Careful readers will note the mismatch. If you add commas, you signal the clause is non-restrictive, but then the sentence implies there is only one car (already identified) — which may not be what you mean. Both the pronoun choice and the comma placement carry real semantic weight.
Question 3 True / False
'My laptop, which I bought in 2022, is slow' contains a non-restrictive relative clause because the laptop is already fully identified, and removing the clause doesn't change which laptop is meant.
TTrue
FFalse
Answer: True
Correct. 'My laptop' fully identifies the noun — there is (implicitly) only one laptop belonging to the speaker. The 'which I bought in 2022' clause adds supplementary information, but removing it leaves 'My laptop is slow,' which still refers to the same specific laptop. The commas signal this non-restrictive status, and 'which' is the standard pronoun for non-restrictive clauses.
Question 4 True / False
'That' and 'which' refer to different types of nouns: 'that' is for animate or human nouns, and 'which' is for inanimate objects.
TTrue
FFalse
Answer: False
The 'animate vs. inanimate' distinction governs 'who/whom' (for people) versus 'which/that' (for things or sometimes groups). The distinction between 'that' and 'which' is entirely different: it is about whether the clause is restrictive (essential — use 'that') or non-restrictive (supplementary — use 'which' with commas). Both 'that' and 'which' refer to things (or animals or groups), not to people.
Question 5 Short Answer
Explain how using 'which' instead of 'that' in a restrictive clause (without commas) can actually change what a sentence means.
Think about your answer, then reveal below.
Model answer: A restrictive clause with 'that' identifies which specific member of a category is meant — it narrows the noun down. A non-restrictive clause with 'which' (and commas) presupposes the noun is already identified and just adds extra information. If you use 'which' without commas in a context where restriction is needed, you imply the noun is already uniquely identified when it isn't, potentially confusing which entity is being referred to or implying there is only one when there are many.
Consider: 'The dogs that bit the mail carrier were quarantined' (restrictive — only the biting dogs, not all dogs). 'The dogs, which bit the mail carrier, were quarantined' (non-restrictive — implies all the dogs bit the mail carrier). The pronoun choice and comma usage together do genuine semantic work, not just stylistic work.
