This is one of several prototypes for the 32nd version of SIGIL script, finished at a later date. It begins to express the phonemic relationships of version 32, though does not yet have all the requirements of the language.
Except for the labial and dental consonants, phonemes can be derived from the vowel regions.
*in the E family, the second plain vowel is the closer form /e/.
Note that long fricatives and long nasals are syllabic-final only. Here is the full set of modifiers shown with P family bases:
The /s/ and /z/ bases are not part of the main series above, but are adapted from the T series. Plain unvoiced lateral fricative has its own glyph. Other fricatives of the L region and /h/ use the vowel base.
A numeric-style series of breaks is available, plus a capitalizer.
This is the beginning of Shakespeare’s sonnet 18 again (transliteration), for comparison with other versions of SIGIL.
“Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate;
Rough winds do shake the darling buds of May,
And summer’s lease hath all too short a date.”
