I in Morse Code
The letter I in Morse code is ..: two dots, sounded “di-dit”. It is one of the shortest letters in the code and the first word of “I love you”.
What Does I Look Like in Morse Code?
I has 2 signals (2 dots) and takes 3 timing units to send. I is the second step of the dot ladder: E is one dot, I is two. Because it is so short, it is easy to miss when it sits between longer letters. See it next to every other letter on the Morse code alphabet chart.
Words That Start With I in Morse Code
| Word | Morse code | Letters |
|---|---|---|
| IN | .. -. | I N |
| IS | .. ... | I S |
| IT | .. - | I T |
| ICE | .. -.-. . | I C E |
| IDEA | .. -.. . .- | I D E A |
Each word starts with ... A space separates the letters. Type any other word into the Morse code translator to hear it.
Letters Easily Confused With I
E (one dot)
. · dit
S (three dots)
... · di-di-dit
M (the opposite of I)
-- · two dashes
A (last dot becomes a dash)
.- · dot dash
I is two dots and M is two dashes, so they are opposites. I also sits between E and S on the dot ladder, which is why spacing and tempo matter when you hear it. For a step-by-step method, read how to identify a letter from its Morse pattern.
How to Remember I in Morse Code
Say it out loud
“Di-dit” is two quick blips, like a short double tap.
Two dots, two letters
I has exactly two signals, the same as A, N and M. Those four are the complete set of two-signal letters.
Hear it in I love you
“I love you” starts with I (..). The I love you in Morse code page shows the full phrase.
Drill it
Hear I among E, S and M in the Morse code practice quiz.
How Long Does I Take to Send?
I is 3 units long: 1 for each of the two dots and 1 for the gap between them. A dot is 1 unit and a dash is 3. The Morse code timing guide explains how speed changes the length of a unit.
| Speed | One unit | Time to send |
|---|---|---|
| 5 WPM | 240 ms | 720 ms |
| 10 WPM | 120 ms | 360 ms |
| 15 WPM | 80 ms | 240 ms |
| 20 WPM | 60 ms | 180 ms |
| 25 WPM | 48 ms | 144 ms |
I in Radio and Real-World Morse
The two-signal letters
A, I, M and N are the only letters made of exactly two signals. The Morse code alphabet chart groups letters by length.
IN versus F
IN (.. -.) and F (..-.) use identical signals. Only the gap tells them apart. Read how to decode Morse code without spaces.
India in the NATO alphabet
On voice radio, I is spoken “India”. Morse code vs the NATO alphabet explains both systems.
Short words with I
I starts IN, IS and IT, some of the most common words in English. Hear them in the Morse code translator.
How Efficient Is I in Morse Code?
Alfred Vail gave common letters short codes after estimating how often each letter is used. Comparing I’s share of English text with the length of its code shows how well that plan worked for this letter.
| Measure | I |
|---|---|
| Share of letters in English text | 7% |
| Frequency rank (of 26 letters) | 5th |
| Morse code length | 3 units |
| Other letters with the same length | T |
| American Morse (US landline telegraph) | .. (same as International) |
I is the fifth most common letter and, with T, shares the second-shortest length of 3 units. Two dots are quick to send, which suits a letter that appears in so many everyday words.
