Hi in Morse Code
“Hi” might be the easiest word in all of Morse code: six dots, zero dashes. If you learn one word today, make it this one.
How to write “hi” in Morse code
Hi in International Morse code is ···· ·· — the letter H (four dots) followed by the letter I (two dots):
That's the entire word: six dots, no dashes anywhere. The only thing separating it from a random string of dots is the small pause between the letters — four dots, a breath, two dots. That makes HI a perfect first lesson in why spacing matters in Morse code: run the letters together and you'd have six dots, which reads as something else entirely.
How it sounds
In operator speech: di-di-di-dit di-dit — a quick drum-roll, a beat of silence, then two taps. Type HI into the Morse code translator and press Play; at slow speed you'll clearly hear the letter gap doing its job. Then nudge the speed up and hear the word tighten into a crisp little rhythm.
Fun fact: HI means laughter
In amateur radio shorthand, HI HI is how operators laugh — it's the Morse equivalent of “haha.” The rhythm of ···· ·· ···· ·· supposedly mimics the sound of chuckling, and operators have been sending it for over a century. So when you learn HI, you've technically also learned to laugh in Morse code. You'll find more operator slang in our history of Morse code.
Where to go next
Once HI takes about three seconds to send, step up to HELLO — it adds L and O to your vocabulary. Then try the confirmations YES and NO, and you'll have a working mini-conversation. All of them appear with audio on the common words page, and the learning guide turns this into a full study plan.
Try it yourself
Open the Morse code translator, type HI, and press Play to hear it — or turn on the flash and vibrate options to see and feel the rhythm. You'll find more everyday examples on our common Morse code words page, and a full study plan in the guide to learning Morse code.
Frequently asked questions
Hi is ···· ·· — H (four dots) then I (two dots). No dashes at all, which makes it the easiest word to learn.
It’s Morse laughter — the equivalent of “haha.” The bouncing rhythm of ···· ·· ···· ·· has meant a chuckle on the airwaves for over a century.
S is ···; HI is ···· ·· with a clear pause between the letters. That pause is the whole difference — in Morse, spacing carries as much meaning as the signals.
