Reverse dictionary

A reverse dictionary is a dictionary alphabetized by the reversal of each entry:
 * kcots (stock)
 * kcotseid (diestock)
 * kcotser (restock)
 * kcotsevil (livestock)

Before computers, reverse dictionaries were tedious to produce. The first computer-produced was Stahl and Scavnicky's A Reverse Dictionary of the Spanish Language, in 1974. The first computer-produced reverse dictionary for a single text was Wisbey, R., ''Vollständige Verskonkordanz zur Wiener Genesis. Mit einem rückläufigen Wörterbuch zum Formenbestand'', Berlin, E. Schmidt, 1967.

Definition
In a reverse word dictionary, the entries are alphabetized by the last letter first, then next to last, and so on. In them, words with the same suffix appear together. This can be useful for linguists and poets looking for words ending with a particular suffix, or by an epigrapher or forensics specialist examining a damaged text (e.g. a stone inscription, or a burned document) that had only the final portion of a word. Reverse dictionaries of this type have been published for most major alphabetical languages.

Applications
Applications of reverse word dictionaries include:
 * Simple rhyming dictionaries, to the extent that spelling predicts pronunciation.
 * Finding words with a given suffix (i.e., meaningful ending), like -ment.
 * Finding words with the same ending as a given word, even if the sequence is not meaningful.
 * Setting or solving word puzzles, such as -gry or the earlier -dous puzzle (find words ending in some way), or crossword puzzles.

Construction
Reverse word dictionaries are straightforward to construct, by simply sorting based on reversed words. This was labor-intensive and tedious before computers, but is now straightforward. By the same token, reverse dictionaries have become less important since online word lists can be searched dynamically.
