Morse Code Alphabet

Morse Code Letters (A–Z)

Each letter of the English alphabet with its International Morse code, the way it sounds (dit for a dot, dah for a dash) and a button to hear it. Common letters such as E and T are the shortest, which is why Morse code is quick to send.

Morse Code Numbers (0–9)

Every number is five symbols long. For 1 to 5, count the dots at the start; for 6 to 0, count the dashes at the start (0 is five dashes).

Morse Code Punctuation and Symbols

Punctuation codes are longer, usually five or six symbols. The ! sign is not part of the official ITU list but is widely understood.

How to Memorize the Morse Code Alphabet

1. Learn the sound, not the picture. Say each letter out loud as dits and dahs (A is "di-dah", not "dot dash"). Operators recognise letters by rhythm, and counting dots slows you down later.
2. Start with the shortest letters. Learn them in groups by length:
   • 1 symbol: E T
   • 2 symbols: A I M N
   • 3 symbols: D G K O R S U W
   • 4 symbols: B C F H J L P Q V X Y Z
3. Use opposite pairs. Swap every dot and dash and you get another letter: E (.) and T (-), I (..) and M (--), S (...) and O (---), A (.-) and N (-.), K (-.-) and R (.-.), D (-..) and W (.--), G (--.) and U (..-).
4. Use mirror pairs. Read a code backwards to get its partner: B (-...) and V (...-), F (..-.) and L (.-..), Q (--.-) and Y (-.--). A and N, D and U, G and W are mirror pairs too.
5. Numbers follow one rule. Five symbols each: 1–5 start with that many dots, 6–9 start with (number − 5) dashes, and 0 is all dashes.
6. Learn at full speed with extra spacing. Play each character at around 18–20 words per minute but leave longer gaps between characters (Farnsworth spacing) so you learn the sound of the whole character.
7. Practise real words. Short words like SOS, Hi, Yes and Hello combine letters you already know. Type your own words into the Morse code translator to hear them.

Practice the Morse Code Alphabet

Listen and type the character, read a code, key it yourself on a big tap key, or copy whole words. The drill follows the Koch method: it starts with K and M and unlocks a new character each time you reach 90% accuracy. You can also pick letters, numbers, punctuation or your own set.

Pronunciation Guide for Morse Code

In the world of Morse code, understanding how to pronounce the symbols is essential for effective communication. Here's a brief guide on how to pronounce Morse code symbols:

Dot (.) - "Dit": The dot, often referred to as "dit," is the shortest Morse code symbol. When spoken, it's pronounced as "dit," rhyming with "fit." Imagine it as a quick, sharp sound. Inside a character it is shortened to "di", so S is "di-di-dit".

Dash (-) - "Dah": The dash, known as "dah," is the longer Morse code symbol. When spoken, it's pronounced as "dah," rhyming with "saw." A dash lasts three times as long as a dot.

Spacing: In Morse code, the spacing between symbols within a character is typically the length of one dot (dit), while the spacing between characters within a word is the length of three dots (dits), and the spacing between words is the length of seven dots (dits). This spacing ensures clarity in Morse code communication.

Example: The Morse code for the letter "A" is ".-" (a dit followed by a dah), so you say "di-dah".

Frequently Asked Questions

How many characters are in the Morse code alphabet?

International Morse code has 26 letters (A–Z), 10 numbers (0–9) and a set of punctuation marks and symbols. Every letter uses one to four dots and dashes, and every number uses exactly five.

What is the easiest way to learn the Morse code alphabet?

Learn each character by its sound rather than by looking at dots and dashes. Start with the short letters E, T, A, N, I, M, S and O, practise a few minutes every day, and add new letters once you recognise the current ones instantly.

How are numbers written in Morse code?

Numbers always use five symbols. 1 to 5 start with dots and end with dashes (1 is .----, 5 is .....), while 6 to 0 start with dashes and end with dots (6 is -...., 0 is -----).

Does Morse code have lowercase letters?

No. Morse code has no upper or lower case, so "a" and "A" are both sent as .- (di-dah).
