Word Letter Change
Changing letters in a word
Change a word into another
dCode has a tool for creating a word ladder, a word game transforming one word to another by changing only one letter at each step:
| S | T | A | R | T |
| - | - | - | - | - |
| - | - | - | - | - |
| T | O | E | N | D |
Encrypt a message by changing its letters
dCode has many ciphers that replace letters with others (a cryptographic method called substitution cipher), the best known is the Caesar code.
Answers to Questions (FAQ)
What is a letter change in a word? (Definition)
Changing a letter in a word is a linguistic or algorithmic operation that consists of modifying one or more letters of a word to create another.
How to change a letter in a word?
The best way to replace a letter from a word to make another word is to use dCode that will try all possibilities (only one letter or more than one letter changing)
If the position of other letters is kept unchanged (search for paronym):
Example: From the word LETTER, by switching the first letter with a B, make the word BETTER.
If letters can be scrambled, then:
Example: From the word LETTER, by changing one letter without keeping the position of the letters, make the existing words TESTER (+S -L) or STREET (+S -L).
If no letter is changed, see anagrams.
The change may possibly consist of removing letters in a word (without adding any) or adding letters in a word (without deleting any)
How not to change any letter in a word?
To keep the letters but only reorder them, use the anagram generator.
How to search for paronym?
A paronym is a word that looks like another word, both visually and phonetically. To search for a paronym, search for a word by keeping letter order and changing a few letters (1 or 2).
What is the distance between 2 words?
To calculate the distance between two words, there is the Levenshtein distance, which counts the minimum number of operations (insertions, deletions, substitutions/replacing) necessary to transform one word into another.
Example: The distance between KITTEN and SITTING is 3 (replace K with S, E with I, and add G).
