Answers to Questions (FAQ)

What is a semordnilap? (Definition)

A semordnilap is a word where the letters can be read left to right or right to left to give another meaningful word. This definition can be extended from words to groups of words or even to sentences.

Example: STAR and RATS are semordnilaps

The semordnilap differs from the palindrome in that the reverse reading is not necessarily identical. All palindromes are semordnilaps, but not all semordnilaps are palindromes.

Note: semordnilap is the word palindromes read backwards.

What is the list of Semordnilaps in English?

The list of words anacycliques/volvograms/reversgrams is quite large, this list represents the most common ones (use the tool above to get more words):

STRESSED <=> DESSERTS

DELIVER <=> REVILED

ANIMAL <=> LAMINA

DEPOTS <=> STOPED

DIAPER <=> REPAID

DRAWER <=> REWARD

LOOTER <=> RETOOL

MURDER <=> REDRUM

REDIPS <=> SPIDER

DEBUT <=> TUBED

DEEPS <=> SPEED

DEVIL <=> LIVED

PEELS <=> SLEEP

SERIF <=> FIRES

STEEL <=> LEETS

SWAP <=> PAWS

All these words exist spelled in one direction or the other.

What is the difference between a semordnilap and a palindrome?

Semordnilap can be read in both direction and can be a different one. A palindrome must be identical backward.

Example: LEVEL is a palindrome (but also a semordnilap)

Example: SEMORDNILAP is a semordnilap, which can be read PALINDROMES backward.

NB: all semordnilaps are anagrams.

What is an ambigram?

An ambigram is a writing (or drawing) that can have a 2-way reading. For example according to a symmetry, it is in a sense a graphic variant of a palindrome.
