Morse code thus determines the dot length. It is common to assume that a word is 5 characters long. There are two common typical words: "PARIS" and "CODEX". PARIS mimics a word rate that is typical of natural language words and reflects the benefits of Morse code's shorter code durations for common characters such as "e" and "t". CODEX offers a word rate that is typical of 5-letter code groups (sequences of random letters). Using the word PARIS as a standard, the number of dot units is 50 and a simple calculation shows that the dot length at 20 words per minute
Morse code for non-Latin alphabets not have a Morse equivalent, with Е used instead. Hebrew letters are mostly represented using the Morse representation of a similar-sounding Latin letter (e.g. "Bet" ב≡B); however the representation for several letters are from a Latin letter with a similar shape (e.g. "Tet" ט ≡U, while "Tav" ת≡T). See also The following telegraph code table is adapted from one given by Ashok Kelkar, where the Latin letters are encoded as per the International Morse code standard. Some variations on this code exist, and there have been some attempts to introduce other telegraph codes to add efficiency and make it suitable
