Morse code mnemonics is a way to help you remember Morse code. Morse code is a code using dots and dashes that stand for letters in the alphabet and numbers. Morse code mnemonics is a way of making up sentences or stories that have words that start with the same letters as the Morse code. For example, if you wanted to remember the Morse code for S, you could make up a sentence like "Sister sells seashells by the seashore" and remember that the first word starts with S and that the letter S in Morse code is "···−−−".
