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.^[1]

Definition

In a reverse word dictionary, the entries are alphabetized by the last letter first, then next to last, and so on.^[1][2] 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.
