No one needs to be told that the present tense of the verb “to drink” is “drink.” But what about the past tense? Is it “yesterday I drunk two martinis” or “yesterday I drank two martinis”? If you said “drank,” reward yourself with an olive in your next martini.

But many people use “drunk” as the simple past tense. Despite what you hear in the street, that is still considered “wrong” by most usage authorities.

Take one more step back, and talk about what you imbibed before you had those two martinis. Do you say “I had already drunk a beer before the martinis,” or “I had already drank a beer”?

The “right” answer is “drunk.” But, as Bryan A. Garner notes in Modern American Usage, because so many people associate “drunk” with “inebriated,” “drank has encroached on the past participial drunk.” Saying “I had already drank a beer” is at Stage 2 on his Language-Change Index, meaning it’s the equivalent of flunking a Breathalyzer test, but not falling-down drunk.

If you do flunk that Breathalyzer test, are you “drunk driving” or “drunken driving”? Now we’re getting into the realm of judgment (which is probably impaired if you’ve had that beer and the two martinis).

“Drunk” and “drunken” actually have separate meanings. As the Chicago Manual of Style says: “Drunk describes a current state of intoxication {drunk driver}. (By contrast, a drunk—like a drunkard—is someone who is habitually intoxicated.) Drunken describes either a trait of habitual intoxication {drunken sot} or intoxicated people’s behavior {a drunken brawl}.”

But in a usage note, the American Heritage Dictionary of the English Language, fifth edition, says that “as an adjective, the form drunk is usually used after a verb such as be or seem, while the form drunken is used in front of the noun to modify it directly. Garner disagrees, calling “drunken driving” an idiom, because, after all, it is the driver that is drunk, not the driving. He’s perfectly happy with “drunk driving.” Using it, not doing it.

Most everyone agrees that “drunk” is the adjective form after the noun, and that the British “drink-driving” is a nonstarter over here.

But wait, there’s more. Back to the usage note in American Heritage: “A differentiation between drunk and drunken is sometimes made in legal language, wherein a drunk driver is a driver whose alcohol level exceeds the legal limit, and a drunken driver is a driver who is inebriated.” Yeah, right.

The Associated Press Stylebook makes it easier for you: It says to use “drunken driver” and “drunken driving.” (But you are “driving drunk.”)

Got that? Those nuances are enough to drive one to drink.
