There are more English words beginning with the letter 's' than with any other letter. If you use the tool on this page to analyse a text you will, for each type of letter, see the total number of times that the letter occurs and also a percentage that shows how common the letter is in relation to all the letters in the text. Then look at a standard English frequency table and guess the Frequency analysis is less relevant when the message has been encrypted with polyalphabetic encryption (which tends to randomize the frequency of the letters), or when the encryption is homophonic (several different encrypted characters for the same plain letter) or polygrammic (groups of characters replace each letter).

Word Frequency Counter. The method of decryption using frequency analysis has two stages: Work out the frequencies of letters or symbols in the ciphertext and compare the results to the letter frequencies in the language – e.g., we know ‘e’ is the most common letter in English, and ‘the’ is the most frequent word.
