Comprise/Compose Usage Question

Am I wrong or is it incorrect to say something is comprised of a, b and c?

Example #1:
My sad little rock collection comprises a small piece of fancy jasper, a tiger’s eye, a bloodstone, a chunk of quartz and several pieces of feldspar.

Example #2:
Jim’s rock collection is comprised of two diamonds, an emerald, two sapphires, a topaz and a few garnets: his disposable income exceeds mine by a great deal.

In the latter example, comprised should be replaced with composed, right?

Lately, I’ve noticed the phrase ‘comprised of’ used more and more in everyday speech. Imagine my chagrin when I saw it in print! There it was, on the first page of text in America (The Book): A Citizen’s Guide to Democracy Inaction, mocking me. Oh, how it mocked me.

So what’s the straight dope? I understand that language, for better or worse, evolves. Is this the next step in the dumbing-down of – er, I mean evolution of American English? What’s next? Will people find some way to combine modulate and demodulate? Forsooth, that’s crazy talk!

Neither is correct, per strict usage, according to [url=http://dictionary.reference.com/search?q=comprise]Dictionary.com

If you want to be strictly correct, you should say “A small piece of fancy jasper, a tiger’s eye, a bloodstone, a chunk of quartz and several pieces of feldspar comprises my sad little rock collection.”

Are you sure about that, Q.E.D.? Your example contradicts your “strict interpretation” quote (and also has an error in number).

I still uphold the strict usage when copyediting. I feel that it’s a useful distinction.

Ack! You’re right on both counts. I was thinking one thing and typed another.

Now I’m really confused. Is my first example incorrect or not?

It is correct. Sorry for the confusion.

Example 1 is correct in my book. “Comprise” doesn’t take a preposition.

My sad little rock collection comprises bla bla bla.
or
My sad rock is composed of bla bla bla.

This is what I dun learned at skool.

And I wonder how we get into such marvelous tea parties such as this thread.

My question hasn’t been answered yet. Is ‘comprised of’ a grammatical error? Is it a syntax error? Is it – shudder – just a matter of style?

I need answers, folks!

Q.E.D.'s first post, referring to the OED, answered your question, along with jjimm’s post that a preposition is not used with “comprise” (a corollary of the OED’S rule). This is a question of grammar. As noted, usage has become sloppy of late.

“comprised of” is incorrect, but more and more common. It will eventually become correct, unfortunately.

It’s one of those instances where pseudointellectuals try to use a fancy word in place of a perfectly good less-fancy word in order to come off as a fancy speaker, and they end up looking like an idiot. Other examples:

apropos
utilize
epitome

and I know there are more . . .
