<<Which grammatical rule applies to the use of "which" vs. "that"?>>

I regret that there is no fast rule governing this. In general 'which' is used for attributive relative clauses while 'that' is used for restrictive relative clauses, and this is the convention that I follow. It clarifies my thinking and forces me to concentrate on what I am writing. I've looked into the history of this a few years ago and if I get a chance I'll relate a thing or two of interest with regard to it. Right now I'm a bit busy, but this is a favorite subject of mine so I couldn't help but respond. :-)

Which grammatical rule applies to the use of "which" vs. "that"?

Christopher H. notes that Fowler devotes "significant" attention to this question. Well, in The King's English, he devotes 33 full pages to it (83-116, Third edition). That's significant!

Fowler's basic point is that "that" is used to introduce a defining relative clause and "which" (as well as "who") is used to introduce a non-defining one. Concrete examples of the difference:

The book that I read was not very good.
(We had lots of books to choose from. I chose a bad one.)

The book, which I happened to have read, was not very good.
(Mr. X wrote a book. It was not very good. By the way, I read it myself.)

Another way of putting it is that "which" clauses are inessential. You can leave the "which" clause out in sentence (2) without changing the basic meaning. It only amplifies the meaning of the sentence, without "defining" it.

A still simpler rule of thumb: "that" clauses are not set off by commas; "which" clauses are.

For further shades of meaning, read the 33 pages... :-)

The classic treatment of the topic of that and which, from Strunk & White:

>>>>>That is the defining, or restrictive pronoun, which is the nondefining or nonrestrictive . . . .

The lawn mower that is broken is in the garage. (Tells which one)
The lawn mower, which is broken, is in the garage. (Adds a fact about the only lawn mower in question.


The use of which for that is common in written and spoken language ("Let us now go even unto Bethlehem, and see this thing which is come to pass"). [edit: how's that for a nifty example of punctuation!] Occasionally which seems preferable to that, as in the sentence from the Bible. [edit: don't you love it? "The" Bible. King James, of course.] But it would be a convenience to all if these two pronouns were used with precision. The careful writer goes which-hunting, removes the defining whiches, and by doing so improves his work.<<<<<

A quickie from James J. Kilpatrick:
>>>>>Rule of thumb: If the qualifying phrase is set off by commas, use which, if not, use that.<<<<<
