Morse Code Dictionary

Type anything into the search box — a letter (A–Z), a number (0–9), a word like "hello", a Q-code like "QTH", a prosign like "AR", or a Morse pattern like "·− ··". The dictionary searches across all character types simultaneously and returns rich result cards showing the pattern, audio playback, confusable pair warnings, English frequency rank, and a direct link to the full deep-dive reference page for that character. Results update as you type with a 180ms debounce to avoid lag.

Reverse lookup lets you identify a Morse character from its dot-and-dash pattern. Scroll down to the Reverse Pattern Lookup tool. Tap the · (dot) and − (dash) buttons to build a pattern — or type directly using full stops and hyphens on your keyboard. Each space separates characters: "·− ··" decodes as A then I. The tool handles letters A–Z, numbers 0–9, punctuation marks, and prosigns. Click "Play Pattern" to hear the audio of what you entered.

The alphabet page (/morse-code-alphabet/) gives you a full deep-dive into each letter — mnemonics, mirror pairs, Koch method ordering, the binary tree, a practice trainer, and per-letter audio. The prosign page covers all 10 prosigns with their full operational context. The Q-code page covers all 20+ Q-codes with their radio usage. This dictionary does none of that — instead it gives you instant cross-type search (one box that finds letters AND Q-codes AND prosigns simultaneously), reverse pattern lookup, a phrase translator, and a character compare tool. The two approaches complement each other rather than duplicate.

The most commonly confused pairs are: E (·) and I (··) — one dot vs two; T (−) and M (−−) — one dash vs two; A (·−) and N (−·) — same symbols reversed; K (−·−) and C (−·−·) — C adds one more element; U (··−) and V (···−) — V adds one more dot; R (·−·) and L (·−··) — L adds a dot at the end; D (−··) and B (−···) — B adds a dot; W (·−−) and J (·−−−) — J adds a dash. Search any of these characters in this dictionary, then use the ⊕ Compare button to view confusable pairs side by side.

Yes. Every search updates the page URL with a ?q= parameter — for example, /morse-dictionary/?q=hello or /morse-dictionary/?q=QTH. Copy the URL from your browser address bar to share exactly what you searched for. When someone opens your link the search is pre-filled and results are shown immediately. The page also stores your 8 most recent searches in localStorage and shows them as quick-access chips below the search box.

The phrase translator converts any English text to Morse code in real time as you type. It handles all 26 letters A–Z, digits 0–9, and common punctuation marks. Word boundaries are represented by "/" (slash) in the Morse output — the standard ITU notation for inter-word spacing. Click "Play Audio" to hear the phrase played through your browser speakers using the Web Audio API. The "Copy Morse" button copies the dot-dash text to your clipboard. No internet connection is needed after the page loads.

Yes. All Morse data, search logic, reverse lookup, phrase translator, character compare, and phrase library are built into the JavaScript file. Audio is generated using the Web Audio API — no audio files are downloaded. Once the page loads it works completely offline. Your recent search history is saved in localStorage and persists between visits without any server connection.
