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 Morse code for non-Latin alphabets This is a summary of the use of Morse code to represent alphabets other than Latin. The Greek Morse code alphabet is very similar to the Latin alphabet. It uses one extra letter for Greek letter "Χ" and does not use the codes for Latin letters "J", "U" and "V". The "tonos" is not transmitted in Morse code; the receiver can simply infer which vowels require one. The "Greek diphthongs" presented in the bottom three rows of the table are specified in old Greek Morse-code tables but they are never used in actual communication, the
