Reverse dictionary

Last updated

A reverse dictionary is a dictionary alphabetized by the reversal of each entry:


kcots (stock)
kcotseid (diestock)
kcotser (restock)
kcotsevil (livestock)

Another variant alphabetizes by suffix.[ citation needed ]

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]


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 of reverse word dictionaries include:


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. For example, using the Unix commands rev and sort allows the following one-liner program to produce a reverse dictionary of the file "dict":

rev < dict | sort | rev 

By the same token, reverse dictionaries have become less important to the extent that online word lists can be searched dynamically.

Dictionary Collection of words and their meanings

A dictionary is a listing of words in one or more specific languages, often arranged alphabetically, which may include information on definitions, usage, etymologies, pronunciations, translation, etc. or a book of words in one language with their equivalents in another, sometimes known as a lexicon.

The -gry puzzle is a popular word puzzle that asks for the third English word that ends with the letters -gry other than angry and hungry. Specific wording varies substantially, but the puzzle has no clear answer, as there are no other common English words that end in -gry. Interpretations of the puzzle suggest it is either an answerless hoax; a trick question; a sincere question asking for an obscure word; or a corruption of a more straightforward puzzle, which may have asked for words containing gry. Of these, countless trick question variants and obscure English words have been proposed. The lack of a conclusive answer has ensured the enduring popularity of the puzzle, and it has become one of the most frequently asked word puzzles.
