Welcome to ShawAlphabet.com, the definitive online hub for mastering the Shavian script—George Bernard Shaw’s elegant phonetic alphabet that reimagines English spelling. Whether you’re a linguist, a language enthusiast, or simply curious about constructed scripts, this guide will walk you through adding vowel length and stress diacritics, turning ordinary English into clear, unambiguous Shavian text.

Explanation

The Shavian alphabet, named after its creator George Bernard Shaw, was designed in 1917 to provide a one‑to‑one mapping between English phonemes and graphemes. Unlike conventional English spelling, which is riddled with irregularities, Shavian spells each sound exactly once, eliminating ambiguity and making reading and writing far more straightforward.

How It Works

Shavian contains 48 letters: 24 consonants, 12 vowels, and 12 ligatures that represent common digraphs. Each letter corresponds to a single phoneme found in English. The letters are grouped into three families—consonants, vowels, and ligatures—making it easier to learn the inventory.

Family Count
Consonants 24
Vowels 12
Ligatures 12
Total 48

Adding Vowel Length Diacritics

Unicode assigns two combining marks to Shavian. The Vowel Length Mark (U+104A0) is a dot placed directly above the vowel to indicate a long sound, e.g., /i:/ as in “see”. The Stress Mark (U+104A1) is a short horizontal line above the vowel, marking primary stress.

Typing the length mark: type the vowel, then press Ctrl+Shift+U followed by 104A0 (or paste the character). On many systems you can use the virtual keyboard on ShawAlphabet.com, where a button labeled “ː” inserts the length mark automatically.

Adding Stress Diacritics

The stress mark (U+104A1) is added in the same way as the length mark. It is placed over the vowel that carries the primary stress. For example, the word “photograph” is written in Shavian as ⱵⱶⱰːⱵⱵⱶː, with the stress mark over the first vowel.

Because these are combining characters, they do not alter the base letter’s code point, making them easy to insert into existing Shavian text.

Visual or Interactive Example

English Shavian (with diacritics)
see Ⱶː
tide ⱶːⱵ
about ⱵⱶⱵːⱠ
mother ⱢⱶⱰːⱵⱰ
understand ⱠⱵⱰːⱵⱶⱠⱵⱶⱰ

Examples

  • “Light” – ⱪⱶ (no diacritics needed)
  • “Dream” – ⱪⱶⱠ
  • “Time” – ⱶːⱵ
  • “Beautiful” – ⱠⱵⱶⱠⱵːⱠⱶⱵ
  • “Philosophy” – ⱵⱶⱰːⱠⱰⱶⱰ
  • “Elephant” – ⱰⱵⱶⱠⱶⱠ
  • “University” – ⱠⱵⱶⱰːⱠⱵⱶⱰ
  • “Knowledge” – ⱠⱰⱶⱠⱰⱶ
  • “Thunder” – ⱠⱰⱶⱰⱵ
  • “Success” – ⱠⱵⱶⱵⱶ

Practical Exercise

Convert the following sentence into Shavian, adding vowel length and stress diacritics where indicated: “The rain in Spain stays mainly in the plain.”

  1. Identify the stressed syllables: “rain”, “Spain”, “mainly”, “plain”.
  2. Mark long vowels with U+104A0.
  3. Mark primary stress with U+104A1.

Answer Key:

ⱵⱶⱰⱵːⱰ ⱠⱵⱶ ⱠⱰⱶⱰⱶ ⱰⱶⱠⱶⱰː ⱠⱠⱰⱶⱰ ⱠⱵⱶⱰ ⱠⱰⱶⱰⱶ ⱠⱰⱶⱠⱶⱰⱶⱰ

Common Mistakes

  • Confusing the diacritic U+104A0 (length) with U+104A1 (stress) because both appear as a small mark above the vowel.
  • Forgetting to add the stress mark on the first syllable of a word, which can change the meaning in poetry.
  • Typing the diacritics before the base vowel, resulting in a rendering error on some fonts.
  • Using the ligature letters for consonant clusters that are actually separate phonemes.
  • Assuming the Shavian alphabet is accent‑specific; it is designed to be neutral across British, American, and other English accents.

Historical Context

George Bernard Shaw, a prolific playwright and critic, devised Shavian in 1917 as part of his campaign for spelling reform. The alphabet first appeared in his 1917 play Androcles and the Lion, where the protagonist speaks in Shavian. Although it never gained mainstream adoption, the script has survived as a fascinating linguistic experiment and is now supported by Unicode since 2005.
