Hyphen (-) in Morse Code
-....-
A dash bracketing four dots on both sides: — · · · · — . Six symbols altogether, making the hyphen longer than any plain letter in the alphabet — a genuinely surprising length for a mark most people barely think twice about.
An Accidental Pattern
Group the hyphen's six symbols as one-four-one and the pieces read T, H, T — a dash, four dots, then a dash again, which happens to line up with the letters T and H purely by arithmetic rather than by any documented naming convention. It's still a useful shortcut: three familiar chunks instead of six symbols held in mind all at once.
Why It's Longer Than Most Letters
Like most punctuation in the code, the hyphen is deliberately longer than an ordinary letter so it's harder to mistake for one mid-message — a genuine practical concern in an era when hyphenated compound words and dates needed to travel clearly over a noisy wire or weak radio signal.
Frequently Asked Questions
Is the hyphen sent often in real Morse traffic, given how long its code is?
Not especially — hyphenated words and date ranges come up, but nowhere near as often as ordinary letters, so the length rarely becomes a practical burden despite being six symbols long.
Does the hyphen's code have a symmetry worth noticing?
Yes, informally — split into three parts, it happens to read T, H, T, since T's single dash brackets H's four dots on both ends.
