OK in Morse Code
--- -.-
"OK" is famously the most successful two-letter word in the world, and in Morse it's compact and tidy: --- -.- . It's the all-purpose acknowledgment — "got it," "fine," "agreed" — which makes it one of the handiest short signals to know. Quick to flash or tap, "OK" is the kind of word that makes coded conversation feel effortless.
Letter-by-Letter Breakdown
| Letter | Morse | Sound (di / dah) |
|---|---|---|
| O | --- | dah-dah-dah |
| K | -.- | dah-di-dah |
Two letters, both dash-leaning. O is the three dashes (---) and K is dash-dot-dash (-.-). So "OK" opens with three long signals and closes with a dash-dot-dash, making it sound firm and confident — almost all dashes, with a single dot in the K as the only short beat.
How to Send “OK” in Morse Code
"OK" is the perfect acknowledgment in a coded exchange: someone sends a message, you flash "OK" to confirm you received it. It's short enough to tap discreetly on a hand or table. Because it's so dash-heavy, it doubles as good practice for the three-dash O and the common dash-dot-dash K, two patterns you'll meet again and again.

Tap it

Blink it
Signal it with your eyes or a subtle nod — quick for a dot, held for a dash — a silent way to pass "OK" across a room.
Flash it
Use a flashlight or phone light: a brief flash is a dot, a long flash is a dash. Press Play above to hear the timing first.
