Dot Dash Reverse Lookup
You have the pattern — on a bracelet, in a puzzle, tapped out by a friend, half-remembered from a movie — and you need the letter. This tool reads morse in the direction people actually need at 2 a.m.:: symbols in, meaning out. Paste dots and dashes in any common notation.
The short patterns, decoded at a glance
Most reverse lookups are for the shortest patterns — they're what people see on jewelry and in logos. Here are the classics:
| Pattern | Letter | Say it | Famous for |
|---|---|---|---|
| · − | A | di-dah | the first letter most people learn |
| − · | N | dah-di | A's mirror twin |
| · − · | R | di-dah-dit | radio's initial, "roger" |
| − · − | K | dah-di-dah | ham prosign: "go ahead" |
| · · · − − − · · · | SOS | di-di-dit dah-dah-dah di-di-dit | the distress call |
| · − · − · | AR / + | — | "end of message" prosign |
For the complete table both ways — letter to pattern and back — the interactive chart plays every character as audio, and the translator converts full messages in either direction.
Why "what does this mean?" is morse's most common question
The pattern travels without its meaning. People inherit beaded bracelets, spot dot-dash motifs in tattoos and logos, find coded lines in games and films, and photograph jewelry they're thinking of buying — then meet the pattern first and the code never. Reverse lookup is the door in. It's also how most people learn: seeing · − and being told "that's A" plants the sound-before-symbol habit that the whole learning method depends on.
If your pattern comes from an image rather than text, try the image decoder; from a recording, the audio decoder. And if you want to turn meaning back into pattern — for a tattoo or bracelet design — the translator's forward direction does that in one paste.
Frequently asked questions
What does dot dash mean in morse code?
Dot dash (· −, usually written .-) is the letter A. It's the classic beginner pattern: one short signal, one long signal, pronounced di-dah.
What is dot dash dot?
Dot dash dot (· − ·) is the letter R. Its mirror twin K (− · −) reverses the pattern. See our letter pages for R and K for the full drill routines.
How do I read a longer pattern like dot dot dot dash dash dash dot dot dot?
That's SOS sent as one unbroken symbol — the distress call. With spaces (··· ––– ··· as S O S) it's just the letters. Paste any pattern into the tool above and it resolves letter by letter using standard 3-unit letter gaps.
Why does my pattern decode to letters I didn't expect?
Spacing is the grammar: the gaps (not the symbols) decide where letters split. If your source wrote the pattern with inconsistent spaces, the decoder reads different letter boundaries. Check the spacing, or compare against the full chart.
