The Morse Code Alphabet

Twenty-six letters, twenty-six rhythms. Below, each letter gets its code, its NATO phonetic name, an English-frequency rank (E is #1), a memory hook, and playable example words. Letters are listed in A–Z order — but if you're learning from scratch, follow the frequency ladder instead: start with E · and T –, add A ·– and N –·, then I ··, M ––… Each rung adds one dot or one dash, so you're never memorizing more than one new element at a time.

Three facts that shrink the alphabet

1. The most common letters are the shortest. E (·) and T (–) are single symbols; A, I, M, N are two; most of the rest are four or five. Morse's designers counted letter frequencies in English before choosing codes — a century before "Huffman coding" formalized the same idea.
2. Mirror pairs halve the work. E/​T, A/N, I/M, D/U, B/V… learn one and flip dots↔dashes for the other.
3. Reversal pairs like A (·–) vs W (·––) differ by one symbol. Chunk the alphabet into families (the "A family" A·–, W·––, J·–––, P·––·, R·–·, L·–··) and you learn seven letters as one pattern plus a tail.

NATO names: the other alphabet

Each card shows a second name — Alfa, Bravo, Charlie… — the NATO radiotelephony alphabet used for spelling words out loud on voice channels. The two alphabets solve the same problem (unambiguous communication) with different tools: NATO uses whole words that survive bad phone lines ("B as in Bravo"), morse uses rhythms that survive bad radio. Every letter page here pairs the two, because in the real world they travel together — a ham might spell a callsign in NATO words on voice, then send it in morse on CW.

Non-English letters exist too

International Morse covers more than A–Z: accented letters have their own patterns — Ä (·−·−), É (··−··), Ü (··−−), Ñ (−−·−−) — and other scripts have full parallel codes (Japanese Wabun, Greek, Cyrillic, Arabic). English traffic never touches them, but they explain some otherwise-mysterious punctuation shapes: several "punctuation" patterns began as non-English letters. The full international table lives in the ITU recommendation; this site covers the English working set completely.

A learning order that actually works

A-to-Z feels natural and teaches badly. Use one of these three orders instead: frequency-first (the card order above — E, T, A, O… highest-value rhythms first), Koch order (K, M, R, S, U… dissimilar sounds that force real listening, used by our Koch trainer), or family-first (learn A, then its relatives R, L, W, J, P for free). All three beat the alphabet song. The full method is on the learn page.
