Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy.
American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph.
Morse code abbreviations are used to speed up Morse communications by foreshortening textual words and phrases. Morse abbreviations are short forms, representing normal textual words and phrases formed from some (fewer) characters taken from the word or phrase being abbreviated.
See media help. SOS is a Morse code distress signal ( ), used internationally, originally established for maritime use. In formal notation SOS is written with an overscore line ( SOS ), to indicate that the Morse code equivalents for the individual letters of "SOS" are transmitted as an unbroken sequence of three dots / three dashes / three ...

Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds.
Greek. The Greek Morse code alphabet is very "similar" to the Latin alphabet. The "similarity" is based first on optical resemblance of each letter, a.k.a glyph, and then secondly on sound. Example, A both in Greek and English is the same glyph and sound (like a in word apple).
Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph , but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points , each corresponding to a letter of the alphabet, a numeral, or some other character.

A telegraph key or Morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy .
