How do the terms sarcastic and sardonic differ?

I once thought “sardonic” implied sophisticated sarcasm, but I’m guessing that isn’t quite right.

Can anyone clarify?

“Sarcastic” would be a smart-ass and “sardonic” would be like sinister.

Well, here’s what dictionary.com has to say on the matter:

But, after reflecting on that, I still don’t see a very clear cut difference.

The way I think of it, “sardonic” means the overt, eye-rolling, “yeah right” style of sarcasm, while just plain sarcasm is more deadpan. I could be wrong though.

Ah here we go - this entry from m-w.com sheds a little light (at least for me):

Seems to me this makes sense. Sardonic describes your internal feelings - derision or scorn. Sarcastic relates to your intent to cause harm by taunting or ridiculing.

That seems right to me. You wouldn’t say that you “surveyed the scene with a sarcastic smile.” Or, alternatively, “a critic famous mainly for his sardonic remarks.” … Although I probably would say the second one.

Does this division - internal v. intent - make sense to anyone else?

I was under the impression that sardonic was just bitter sarcasm.

I think www.dictionary.com may have defined it that way. Makes sense in the context sardonic is usually used in

In my OED, sarcasm says “ironically scornful language.”

Sardonic says “bitterly mocking or cynical.”

I think sardonic covers more than just language, but sarcasm refers to language. I read a book recently where a little girl is described as smiling sarcastically and it bothered me because I never heard of anyone smiling sarcastically before!

Ooh boy was I wrong . Don’t you hate people who don’t know what the f---- they’re talking about ?
