About Eloquacious, from BoardGameGeek:
Eloquacious is one of the 8 games in Dr. Finn's Book of Two-Player Strategy and Word Games. The game consists of one game sheet and requires no other components -- just a pencil for each player.
Eloquacious is a cooperative game in which players are tying to complete a number of goals by filling out a crossword grid. However, only the clue-giver can see the grid.
In each round, the clue-giver, hoping for a specific response that will help fill the crossword grid, gives a clue to the other player. Each response given must be put into a crossword grid, even if it's not the response the clue-giver was hoping for.
