Acrostic

An acrostic is a poem or other form of writing in which the first letter, syllable or word of each line, paragraph or other recurring feature in the text spells out a word or a message. The word comes from the French acrostiche from post-classical Latin acrostichis, from Koine Greek ἀκροστιχίς, from Ancient Greek ἄκρος "highest, topmost" and στίχος "verse"). As a form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval.

Overview

Relatively simple acrostics may merely spell out the letters of the alphabet in order; such an acrostic may be called an 'alphabetical acrostic' or Abecedarius. These acrostics occur in the first four of the five songs that make up the Book of Lamentations, in the praise of the good wife in Proverbs 31, 10-31, and in Psalms 9, 10, 25, 34, 37, 111, 112, 119 and 145 of the Hebrew Bible. Notable among the acrostic Psalms are the long Psalm 119, which typically is printed in subsections named after the letters of the Hebrew alphabet, each of which is featured in that section; and Psalm 145, which is recited three times a day in the Jewish services. Acrostics prove that the texts in question were originally composed in writing, rather than having existed in oral tradition before being put into writing.

Acrostic (puzzle)

An acrostic is a type of word puzzle, related somewhat to crossword puzzles, that uses an acrostic form. It typically consists of two parts. The first part is a set of lettered clues, each of which has numbered blanks representing the letters of the answer. The second part is a long series of numbered blanks and spaces, representing a quotation or other text, into which the answers for the clues fit. In some forms of the puzzle, the first letters of each correct clue answer, read in order from clue A on down the list, will spell out the author of the quote and the title of the work it is taken from; this can be used as an additional solving aid.

An example

For example, two clues in the first part might be:

The second part is initially blank:

If the answer to clue A is JAPAN, then the second part fills in as follows:

Letters 16 and 17 form a two-letter word ending in P. Since this has to be UP, letter 16 is a U, which can be filled into the appropriate clue answer in the list of clues. Likewise, a three-letter word starting with A could be and, any, all, or even a proper name like Ann. One might need more clue answers before daring to guess which it could be.
