Modern English is written with a Latin-script alphabet consisting of 26 letters, with each having both uppercase and lowercase forms. The word alphabet is a compound of alpha and beta, the names of the first two letters in the Greek alphabet.
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
A spelling alphabet (also called by various other names) is a set of words used to represent the letters of an alphabet in oral communication, especially over a two-way radio or telephone. The words chosen to represent the letters sound sufficiently different from each other to clearly differentiate them.
A language may spell some words with unpronounced letters that exist for historical or other reasons. For example, the spelling of the Thai word for 'beer' เบียร์ retains a letter for the final consonant /r/ present in the English word it borrows, but silences it. [91]
Like many other alphabetic orthographies, English spelling does not represent non-contrastive phonetic sounds (that is, minor differences in pronunciation which are not used to distinguish between different words). Although the letter t is pronounced by most speakers with aspiration [tʰ] at the beginning of words, this is never indicated in ...
Similarly to how phonemes are combined to form spoken words, letters may be combined to form written words. A single phoneme may also be represented by multiple letters in sequence, collectively called a multigraph. Multigraphs include digraphs of two letters [2] (e.g. English ch, sh, th), and trigraphs of three letters (e.g. English tch).
Some sources distinguish "diacritical marks" (marks upon standard letters in the A–Z 26-letter alphabet) from "special characters" (letters not marked but radically modified from the standard 26-letter alphabet) such as Old English and Icelandic eth (Ð, ð) and thorn (uppercase Þ, lowercase þ), and ligatures such as Latin and Anglo-Saxon Æ (minuscule: æ), and German eszett (ß; final ...
There are several reasons for this, including: first, the alphabet has 26 letters, but the English language has 40 sounds that must be reflected in word spellings; second, English spelling began to be standardized in the 15th century, and most spellings have not been revised to reflect the long-term changes in pronunciation that are typical for ...
