## Problem

Given a short J phrase, provide the equivalent common English idiom (or vice-versa).

## Constraints

• J phrases must be syntactically valid. That is, they do not produce an error when typed into the most recent J interpreter.
• English idioms must be common, real, and not "close hits". American idioms are preferred to UKisms.
• If you see a J phrase translated to an English idiom, and you feel the J phrase was not the best expression of the idiom, submit the better one.

## Notes

Feel free to submit your own J phrase puzzles. Or even English idioms for a reverse search.

## Discussion

• Is there a better way to express number 2?
• 4 is a syntax error, and more generally it's not obvious what you're aiming for with any of these. A literal translation of 1 would be "unbox ace", while a literal translation of 3 would be "head nor tail" -- these don't seem to be common phrases. And 0 seems useless. Perhaps an example would illustrate the point?
• Perhaps the solution to 0 answers some of your questions? -- RogerHui 2006-05-19 19:40:45

• Yep, Roger got 0.
• You got 3 (10400000 hits for [head nor tail] on Google).
• You did not get 1, which is why it doesn't make sense to you. They can't all be obvious.

• Regarding 4, the J phrases must not produce errors. But 4 is not a J phrase, it is an English idiom. The "puzzle" column may be a J phrase to translate to an English idiom or a English idiom to translate to a J phrase (notice the problem spec says "or vice-versa").

• These early puzzles are easy and meant to stimulate interest in creating harder ones. They're poor witticisms in the sense demonstrated at Essays/Witticisms, which generally derive their translations by their actions (what they do), not their composition (what they're made of).

• #7 is better described as "big deal", seeing as how the dyad ? is "deal" ("roll" is the monad). -- RogerHui 2009-09-28 20:04:38

• Ok, changed & noted.
