S vs H vs 5
Three, four, or five dits — count fails; listen to length of the whole run.
How the International Morse alphabet works: starter letters, lookalikes, timing, and links to the interactive A–Z chart.
Direct answer: The Morse alphabet is 26 International (ITU) letter patterns built from dots and dashes. Meaning comes from element length and spacing — not from the printed dots alone. Use the interactive alphabet chart to hear each letter.
Each Latin letter maps to a unique International Morse pattern. E is one dit (.); T is one dah (-); more complex letters combine those elements with one-unit gaps inside the character.
This page explains how the alphabet works. The Morse code alphabet hub is the click-to-hear chart for daily use.
| Letter | Morse | Why |
|---|---|---|
| E | . | Shortest · most common |
| T | - | Single dah |
| A / N | .- / -. | Mirror pair |
| I / M | .. / -- | Two dits vs two dahs |
| S / O | ... / --- | Three dits / dahs · SOS |
Three, four, or five dits — count fails; listen to length of the whole run.
Same elements, reversed order — rhythm distinguishes them.
Leading dah then dits; wrong gap turns letters into digits.
A printed A–Z without spacing rules is incomplete — read timing.
