Everything visitors most often ask about levidromes — what they are, who named them, how they differ from palindromes and anagrams, and how to find your own.
What exactly is a levidrome?
A levidrome is a word that becomes a different word, with a different meaning, when you read its letters in reverse order. Stop reversed is pots; evil reversed is live; desserts reversed is stressed. Both directions must be real English words, and the meanings must genuinely differ. If the reversal produces the same word, you have a palindrome instead — see the next questions.
Who invented the word 'levidrome', and when?
Six-year-old Levi Budd of Victoria, British Columbia, Canada, coined it in the autumn of 2017. Riding in his mother's car, he noticed that STOP reads POTS backwards, asked what such words are called, and — finding that everyday English had no word for it — built one from his own name, Levi, plus -drome, the ending of palindrome. His family's campaign to get the word recognised drew support from William Shatner and Patricia Arquette and coverage in the Times Colonist, The Star, and CTV News. The full story is in our Journal: The Six-Year-Old Who Put His Name in the Dictionary.
Is 'levidrome' in the dictionary yet?
It has a Wiktionary entry, with citations tracing it through the 2017–2018 newspaper coverage and later books, and it is tracked by word-watchers at major dictionaries. The large print dictionaries have not formally added it yet. That is normal: dictionaries admit a word after it shows widespread, sustained use over years, not months — which is exactly the test Oxford's editors described to Levi's family. Every classroom project, article, and site (including this one) that uses the word is part of the evidence file. Our article How New Words Get Into Dictionaries explains the process in detail.
How is a levidrome different from a palindrome?
A palindrome reads the same in both directions: noon, kayak, level, and the sentence 'A man, a plan, a canal — Panama!' A levidrome changes into a different word when reversed. The two-second test: reverse the word. Same word back? Palindrome. A new word with a new meaning? Levidrome. Our palindromes page lists examples of both families in English and French.
How is a levidrome different from an anagram?
An anagram rearranges letters in any order: listen and silent use the same letters reshuffled. A levidrome permits exactly one rearrangement — a perfect mirror reversal, last letter to first, with nothing moved anywhere else. Every levidrome is therefore a very special kind of anagram, but most anagrams are not levidromes: reversing listen gives netsil, which is not a word. See the glossary for the whole family of word-pattern terms.
What is a semordnilap? Is it the same thing?
Semordnilap — itself 'palindromes' spelled backwards — is the older, technical term for the same pattern, coined in the mid-twentieth century and used by word-game specialists. Levidrome is the plain-English name proposed in 2017, and the one most teachers, journalists, and new collectors now use. Linguists also use anadrome and reversal pair. All four labels describe the same phenomenon; this site uses levidrome because it is the name with the story, and the one a six-year-old can pronounce.
How many levidromes are there in English?
Nobody knows the complete count, because it depends on which dictionary and which rules you apply — whether you accept plurals, past tenses, dialect spellings, and rare words. Strict lists of common words run to a few hundred pairs; generous lists that admit every inflected and uncommon form run higher. This site's dictionary deliberately keeps a conservative core of 48 pairs in which both directions are ordinary, recognisable English words, so that every entry can be trusted in a classroom or a crossword.
What is the longest levidrome?
The most famous long pair — and the longest in our dictionary — is the eight-letter desserts / stressed. Below it sit the seven-letter pairs deliver / reviled and gateman / nametag, and the six-letter pairs drawer / reward and diaper / repaid. Long pairs are rare for a mathematical reason: reversal fixes every letter's position, so each extra letter is another independent chance for the pattern to fail. Our Journal article Famous Long Levidromes is a tour of the hall of fame.
Can a proper name be a levidrome?
For this collection, no. Names, places, brands, and acronyms are excluded, because allowing them would let almost anything qualify and the list would stop meaning anything. The pattern is interesting precisely because it happens between two ordinary dictionary words. (Levi's own name is the honourable exception that proves the rule — it lives in the word levidrome itself, not in the pair list.)
Do other languages have levidromes?
Yes — any language written with an alphabet can produce them, and collectors track them in French, Spanish, Dutch, German, and many other languages. The pairs differ completely from language to language, because they depend on each language's spelling accidents. Finnish and Hawaiian, with their highly regular spelling, are especially rich hunting grounds for palindromes. Our palindromes page includes a French word list as a small taste of wordplay across languages.
How can I find levidromes of my own?
Start short — three- and four-letter words flip most often. Read the world backwards for a day: street signs, menus, shop names, book spines. When a reversal looks promising, check both directions in a dictionary before celebrating; slang, names, and abbreviations don't count. Keep a dated list of your finds, and rank them by how far the meaning travels — pairs where the reversal flips the idea, like evil/live or doom/mood, are the trophies. The field guide in What Is a Levidrome? walks through the method step by step.
I found a pair that isn't in your dictionary. What should I do?
Wonderful — that is exactly how the collection grows. Send both spellings and a short meaning for each word through the contact page. We check every suggestion against standard dictionaries; pairs in which both directions are ordinary English words with different meanings are added with credit to the finder where they wish. Corrections to existing definitions are equally welcome.
Can I use this site in my classroom?
Yes — the whole site is free to use, project, and print for teaching. The For Teachers page has six classroom-ready activities with steps and timings, word lists sorted by length for different ages, and discussion questions. The games (Reverse Six, Memory Match, Word Search) need no accounts, no downloads, and no sign-ups, and they run on classroom tablets and interactive whiteboards.
Why does this site exist?
Three reasons. To keep a trustworthy, fully defined list of pairs in one place; to keep Levi Budd's word in public use, because use is what eventually carries a word into the big dictionaries; and to give the pattern the playground it deserves — games, long reads, and tools for teachers. If the site has a motto, it is the one on the footer of every page: keep looking both ways.
