double acrostic

A double acrostic is a type of word puzzle. It's constructed so that the initial letters of the lines form words, and in some cases, the middle or last letters also form words.1

The Double Crostic, devised in the United States in 1934, is a specific type of double acrostic. In this puzzle, the initial letters of the answers to clues spell out the author and title of a literary work. These letters, corresponding to numbered blanks similar to a crossword puzzle, then form a quotation. The objective is to fill in numbered dashes with words guessed from definitions, then transfer these letters to a diagram to reveal a quotation, with the initial letters spelling the source's author and title.12
