T in Morse code is a single dash: −. Spoken as “dah”, it is the exact mirror of E (·) in the International Morse Code system. E is one dot; T is one dash. Together, these two characters form the foundation upon which the entire 26-letter alphabet is built — every other letter is some combination of dots and dashes built on the same elements.
T is the second most common letter in English after E, and was assigned the second shortest code: a single dash. This means T transmits almost as quickly as E in real use, and experienced operators recognise it instantly as the single long tone that sits alone between other character sounds.
What Is T in Morse Code?
| Letter | Morse Code | Visual (dots and dashes) | Pattern |
|---|---|---|---|
| T | - | − | single dash |
One dash. One long beep. “Dah.” At 20 WPM, the dash lasts 180 milliseconds — exactly three times the duration of a dot. At 5 WPM, it lasts 720 milliseconds. The single long tone is unmistakable in any transmission.
E and T Together — The Foundation Pair
In every standard Morse learning programme, E and T are introduced together as the foundational pair. The logic is simple:
| Letter | Morse Code | Sound |
| E | · | dit — 1 unit (60 ms at 20 WPM) |
| T | − | dah — 3 units (180 ms at 20 WPM) |
Every Morse character is a variation of the E-T pair: 1–4 dots and/or dashes in different combinations. Once the ear can reliably distinguish a short beep from a long beep, the entire decoding system becomes learnable. E and T are the test that the ear is ready. Master these two and all other letters follow logically.

Common Names Starting With T in Morse Code
- Tom: − −−− −− → T O M
- Tyler: − ·−−·· ·−·· ·−· · → T Y L E R
- Tina: − ·· −· · − → T I N A
- Ted: − · −·· → T E D
- Theo: − ···· · −−− → T H E O
T in Ham Radio: CQ and the AR Prosign
The letter T plays a significant role in standard ham radio operating procedure. The CQ call — the universal call for any station to respond — contains T in the second letter: C (−·−·) Q (−−·−). The end-of-transmission prosign AR (· − · − ·) contains T in the second position. And the word TNX (thanks) begins with T, one of the most common ham radio abbreviations.
Real-Life Usage of T
T is the second most used letter in English, showing up in words like “the,” “that,” “this,” and “to.” In Morse code conversations, T gets sent constantly. In the NATO phonetic alphabet, T is “Tango,” a word radio operators say when spelling out words letter by letter to avoid confusion. T in Morse code is also used within the SOS distress signal as the middle letter: S (dot dot dot), O (dash dash dash), S (dot dot dot).
Example Words Using the Letter T
Here are some common words that start with or contain the letter T:
- The
- That
- Tango
- Time
- Talk
- True
- Train
- Top
- Tell
- Turn
Practising Morse code using real words is much more effective than repeating single letters. Try spelling two or three of these words using what you know so far.
Practice: Sending T in Morse Code
Send the letter T by making one single long tap or holding down a Morse key for a brief moment. Practice pairing T and E: dash for T, then dot for E. Tap that pattern several times until you can do it without thinking. Then try spelling the word “TE” or “ET” in rhythm. Short exercises like this build muscle memory fast.
You can also use the Morse Code Translator on this site to hear how T sounds at different speeds. Listening to the correct rhythm is just as important as tapping it yourself.

Frequently Asked Questions: T in Morse Code
What is T in Morse code?
T in Morse code is a single dash: −. It is spoken as “dah” and lasts 3 time units — three times the length of a dot.
How do I tell the difference between E and T by ear?
By duration. E (·) is a brief, short beep — “dit”. T (−) is a longer, sustained tone — “dah”. At 20 WPM, E lasts 60 ms and T lasts 180 ms. With practice, the difference becomes instantly recognisable without any conscious counting.
Is T used in any Morse prosigns?
T appears in several common prosigns. AR (end of message) is · − · − ·, which contains T as its second element. SK (end of contact) is · · · − · −, containing T as its last element.
Conclusion
The letter T in Morse code is –, represented visually as −. Whether you are a complete beginner or brushing up on forgotten knowledge, learning one letter at a time is the most reliable way to build a solid Morse code foundation. T is a letter you will encounter often as your practice progresses, and knowing it well will serve you across words, names, and real transmissions.
Keep practising a little every day. Even five minutes of tapping rhythms or listening to Morse audio will build your skills faster than you expect. Use the Morse Code Translator to test yourself, explore the full learning guide, and keep going through the rest of the alphabet one letter at a time.
