X in Morse Code
-..-
Dash, dot, dot, dash: — · · — . Read the four symbols in either direction and they come out identical — one of only a small handful of genuine palindromes anywhere in the Morse alphabet.
Related Letters
- D (dash-dot-dot) is X with the final dash removed.
- B (dash-dot-dot-dot) shares X's opening three symbols but closes on a dot instead of a dash.
- C (dash-dot-dash-dot) shares X's total length but arranges the dots and dashes differently.
That built-in symmetry makes X one of the more forgiving longer letters to get right by ear, since a listener who catches the shape even slightly out of order will often still land on the correct four symbols.
Frequently Asked Questions
Does X's palindrome shape make it more forgiving to send imperfectly?
In a small way, yes — because the code reads the same forward and backward, a listener who catches the shape slightly out of sequence often still lands on the correct four symbols, unlike most letters where order is everything.
Is X's code really a palindrome?
Yes — dash-dot-dot-dash is identical whether read from the start or the end, one of only a few letters in the alphabet with that property.
