L in Morse Code: ·−··

The letter L in Morse code is ·−··, spoken as "di-DAH-di-dit": one short, one long, then two short. That is 3 dots and 1 dash, with a dash held three times as long as a dot. To remember it, think to-HELL-with-it (only the second syllable is stressed).

Timing: how long each part lasts

Morse timing is built from one unit, the length of a dot. A dash is 3 units, and the silence between the elements of a single character is 1 unit. At 20 words per minute, one unit is 60 ms, so L breaks down like this:

How to signal L

  • Tap it: one short, one long, then two short. A short is a quick tap; a long is a heavier tap, or a quick tap followed by a slight hold, about three times as long.
  • Blink it: one short, one long, then two short. Use quick blinks for dots and slow, deliberate eye closes for dashes, keeping the rhythm steady.
  • Flash it: one short, one long, then two short. Short flashes for dots; for dashes, hold the light on about three times longer. Any flashlight or phone screen works.

How to remember L

Say to-HELL-with-it (only the second syllable is stressed) in rhythm with the code and the pattern sticks: "di-DAH-di-dit".

Words that start with L: Lima ·−·· ·· −− ·−, lamp ·−·· ·− −− ·−−·, ladder ·−·· ·− −·· −·· · ·−·, lake ·−·· ·− −·− ·. The first is L's NATO phonetic name, which operators use to spell aloud.

In the original American Morse code used by railroads, L was a single extra-long dash. The international code replaced it with today's four-element pattern.
