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 mnemonics to remember Morse codes lies in remembering words that begin with each appropriate letter and has so called long vowel (i.e. á é í ó ú ý) for every dash and short vowel (a e i o u y) for every dot. Additionally, some other theme-related sets of words have been thought out as Czech folklore. In Indonesia, one mnemonics commonly taught in scouting method to remember Morse codes lies in remembering words that begin with each appropriate letter and substituting the o vowel for every dash and other vowels (a, i, u, and e) for every dot.
