M in Morse code
M in Morse code is "--": two dashes, spoken "dah-dah". It is one of the 4 two-element letters, so it sits two steps from the root of the Morse code tree, and it is the mirror image of I, which is dot-dot. The 7-day plan teaches M on day 2. At 20 words per minute it takes 420 milliseconds to send.

M at a glance
Where M sits in the Morse code tree
The path through the Morse code tree to M: from the root, a dash to T then a dash to M.
In the Morse code tree a dot branches left and a dash branches right, so every character sits exactly where its own code leads. M sits two steps from the root, directly below T. From M, a dot leads to G and a dash leads to O.

M is easiest to mistake for I, A or N. Practise them back to back until the difference is a sound rather than a count.
How to learn M
7-day plan
The plan teaches M on day 2, together with I, A and N. Learn it by its sound, "dah-dah", at full speed rather than by counting its elements.
In the Koch method it is character 2 of 36.
Practise
Practice brings M back just before you would forget it, in all three skills: copying it by ear, reading it, and sending it yourself.

Questions about M in Morse code
- What is M in Morse code?
- M in Morse code is "--", spoken dah-dah. It is two elements long (dash dash) and takes 420 milliseconds to send at 20 words per minute. It sits two steps from the root of the Morse code tree.
- Which Morse code characters are confused with M?
- M (--) is easy to confuse with I (..), its mirror image with dots and dashes swapped, and with A (.-) and N (-.), each of which differs from it by a single element. Practise them back to back until the difference is a sound rather than a count.
- How do you learn M in Morse code?
- By its sound, not its shape: M is spoken dah-dah. Listen to it at full speed instead of counting its elements. MorseForge's 7-day plan teaches it on day 2, together with I, A and N.
