"Smooth" is definitely still current slang, with a meaning similar to "cool." And "smooth" came first:

> Slang meaning "superior, classy, clever" is attested from 1893. Sense of "stylish" is from 1922.

> A 1599 dictionary has smoothboots "a flatterer, a faire spoken man, a cunning tongued fellow."

It may be time to bring that one back. "Did you see Keith chatting up that girl at the bar? Total smoothboots."

I would say the 1599 sense more accurately reflects the current sense of "smooth" than the 1893/1922 citations do.

Sophisticated used to mean false, as in sophistry: with intent to deceive. So a sophisticated wine, was an adulterated wine, that had something other than fermented grape juice in it.

TIL. I was quite surprised that sophistication used to mean deceptive/misleading behavior.

"Sophistry" still does.

"Silly" is the standard example of semantic shift over what people generally perceive to be a pretty extreme distance: https://www.etymonline.com/word/silly

Or water, presumably?

To the Romans, drinking wine merum (pure) was a sign of barbarity. They drank their wine diluted.

I don't see a mention of "sophisticated" above - was this just a fun fact?

Roman wine was very strong, around 15-20% ABV. No wonder they added water to it (and sometimes lead as a sweetener).

I've never heard anyone use smooth the way everyone uses cool.

[bl4ckneon]

I second this. Linguistics and "slang" is pretty interesting in its own right. I believe that "cool" is more universally used. Usually smooth is used to describe an action that someone did, not really heard it being used in place of "cool".

I tend to agree, smooth is IME also usually (but definitely not entirely) used sarcastically, when someone does something accidentally silly, like bumping into a glass door or similar.

"cool" appears in Shakespeare and in the Coventry Christmas Play with the same meaning it's used for today.
