       | My favorite examples are how prepositions can change the meanings
       | of idioms. For example, to be "down for" something and "down
       | with" something mean the same thing, but to be "down on"
       | something means the opposite. (And going down _to_ X means
       | something very, very different from going down _on_ X. That last
       | example is also interesting from a geeky HN point of view because
       | the preposition imposes a type constraint on the binding of X,
       | which is why I had to use  "X" instead of "something" :-)

         | That's much less true than it used to be! I don't know what

       | 
       | If you enjoy this feeling, I think you would like my word game

       | only 3 spaces blank!

         | Fun game! Though I dispute that people are "very close" to
         | achieving a perfect pattern.
         | 
         | To get a "perfect" pattern you'd need to find three 7 letter
         | words that can stack on rows adjacent to each other to form a 3
         | letter word in each column. Such arrangements _do_ exist, for
         | example:                   o p e r a t e         a r r o w e d
         | r e s e n d s
         | 
         | but they are very rare - I estimate something on the order of
         | 0.002% of combinations of three 7-letter words have any valid
         | arrangements. Assuming that you're using standard ETAOIN letter
         | frequencies, the typical bag of 21 letters will usually have
         | just a handful of combinations of three 7-letter words so a
         | given puzzle has a << 0.1% chance of having a perfect solution.
         | 
         | But there are 12,000x more ways to rearrange 21 tiles within an
         | 8x3 grid, and the word choices are more forgiving as well (if
         | you draw 7 letters from the etaoin frequency distribution,
         | those 7 letters in order are much more likely to form a 3
         | letter word followed by a 4 letter word than they are to form a
         | 7 letter word). Pretty much every puzzle should have at least
         | some solutions fitting within an 8x3.
         | 
         | Additional note: 3 blank spaces is the best non-perfect
         | arrangement, since the grid is only 10 tiles wide. One blank
         | space could only be achieved by a single 23-letter-long word,
         | and two blank spaces could only be achieved by a 10 letter word
         | next to an 11 letter word, and an 11 letter word would not fit
         | inside the 10x10 grid.

       | I'm a big fan of killing time on long drives with friendly word

       | clue word, usually a synonym, but any kind of related word is
       | fair game. They say those two clue words out loud, and the other
       | players have to guess the original rhyming pair.
       | 
       | What makes it fun is trying to reverse-engineer the original
       | rhyme from the clues. It's like solving a little logic puzzle.
       | It's easy to come up with new puzzles, but cracking them can be

       | Inches : Length") in a square, and that most crossword clues
       | could be represented as weird SAT analogies. Or maybe I'm
       | stretching the analogy.

       | But I think that the "Diagonal" that the author suggests for the
       | connection between "Donkey" and "Elephant" and "Party" isn't
       | quite correct. The key is that both the Donkey and the Elephant
       | are a "Party Animal." You can't ignore the "Animal" part, it
       | describes them: they are each the animal that represents their
       | party, the "party animal."
       | 
       | I'm not sure the correct way to represent this in "Square
       | Theory," but it's not just linking "Party" to the animal in
       | question.
