Memory mnemonic

you-too-WOOOON

Say it aloud with the stresses shown. The phrase carries the same dit/dah rhythm as the Morse for U. Once the rhythm sticks the dots and dashes follow.

This is the widely-circulated Scout-meeting variant. Many teachers develop their own — the words don't matter, only that the chosen phrase carries the same dit/dah rhythm.

About U in Morse code

Pattern: ..-
Length: 7 Morse units
Spoken as: Uniform (YOU nee form)
In English text: 2.8% of letters — the 13th most common
Sent backwards: -.. is D
Dots ↔ dashes: --. is G

U takes 7 units to send. 6 letters are shorter and 4 others are the same length. Alfred Vail reportedly counted the type in a printer's case and gave the shortest codes to the letters used most, so frequency and length roughly track each other: U is the 13th most common letter and has the 7th-shortest code.

How long U takes to send

Speed	Unit length	U takes
5 WPM	240 ms	1.7 s
13 WPM	92 ms	0.65 s
20 WPM	60 ms	0.42 s
25 WPM	48 ms	0.34 s

Standard PARIS timing: one unit is 1200 ÷ WPM milliseconds; a dot is 1 unit, a dash 3, and the gap inside a character 1. Add 3 units between letters and 7 between words.

Easily confused with

These are one dot or dash away from U. Mishearing a single element — or clipping one off the end — turns U into one of them, so they are worth drilling side by side.
