It's not at all pretentious to use a well-defined word whose meaning is precisely appropriate. To anyone who needs convincing of this I recommend a large stack of Christopher Hitchens.

What's pretentious is using big words to impress others. Most people who do this actually end up not using such words correctly, since nuances of meaning are hardly their primary concern.

Edit: what I really object to is your implied criterion that anything beyond what "most people" would say must be pretentious. Lord help us if we're supposed to go by "most people".

I think Richard Feynman would disagree with you, and his plain spoken manner is a symbol of how to be smart without being pretentious.

Using uncommon words appropriately doesn't make them any less pretentious unless you really don't know they're uncommon, and Christopher Hitchens, whom I very much like, is hardly someone associated with being unpretentious. Hitchens certainly doesn't suffer fools well.

So anything beyond what's common is pretentious? As I read the definition of the word, that's just wrong. On the other hand, looking things up in a dictionary to find out what they mean is so far from common that, by your definition, I'm being pretentious just for doing so.

Edit: your invocation of the name of Feynman strikes me as gratuitous (oops, I'm being pretentious there) and a textbook example of appeal-to-authority (or rather, it would be one, if you actually were quoting him or had the right to speak for him).

Edit 2: what on earth does "suffering fools well" have to do with being pretentious or not?

I wish there was a voice recognition program for smartphones that kept a running log of uncommon words within earshot. You could then click on the log to go to a definition. (Which would be pre-fetched and cached.)

Well, it's not really worth arguing about, but my appeal to authority was in response to an appeal to authority (Hitchens). If you don't agree the word is pretentious, fine, but to me and many others I presume (since I didn't start this thread, someone else called it pretentious first) do find that people who use uncommon words are being pretentious and trying to sound impressive with their vocabulary. Given a choice to say something plainly or with fancy words, the unpretentious choice is plain talk.

As for the reference to suffering fools, I was merely pointing out why I think Hitchens can be pretentious, but it wasn't really relevant, I agree.

Maybe ostentatious is a more accurate word, but it is a synonym of pretentious. In any case, I really don't care that much, so I won't bother arguing further, if you disagree with me, then let's just agree to disagree and move on to something more productive than arguing about words.

Ok, but I can't resist adding one more! First, it seems we do agree on what's "pretentious": not using uncommon words as such, but doing so to sound impressive with one's vocabulary. Also, I brought up Hitchens not to invoke any kind of authority but rather as rich source material for the inventive and pitch-perfect and endlessly entertaining (and, yes, unpretentious) usage of all kinds of words. It seems we agree on most of that :)

Lastly, I'd like to add something to this conversation that isn't merely being critical. The thing about less common words is that, often, they are not exactly synonymous with more common alternatives. There are often nuances that, consciously or otherwise, add to the meaning of what's being said. While thinking of this I remembered a brief post from Language Log a while back that I thought was brilliant. It takes several examples of forms that have been claimed to be interchangeable (and thus superfluous), and susses out real distinctions between them:

There must be a few people here who find language as interesting as I do, and would enjoy parsing out the examples they give. I'd post it as an item to HN but can't think of a title that could possibly convey the point. Oh well, maybe I'll just post it anyway...

Terrific link!

It's pretentious to say that it's pretentious; in fact, any use of the word pretentious is extremely pretentious, including this one. The use/mention distinction also breaks down for the word 'pretentious': it's not even possible to mention the word without being fatuously pretentious. This is especially true if the criterion for pretentiousness is whether "most people" would know what it is.

'Autodidact' is another matter.

It's IGNORANT to refer to that word as pretentious.

I have seen that attitude from the room temp IQ crowd - never thought I would see it here.

What lead you to believe that posters here have high IQs? Certainly not the articles or comments ;)

Average IQs would be sufficient to make his point. In my part of the world, "room temperature" refers to somewhere in the neighborhood of 75.

I've also met someone who thought it would be neat to be lumped in with the pseudo-intellectuals, because she thought it was a neat sounding word.
