This is another easily hand-written, phonetically constructed alphabet, like others in my Phonological Cypher series. It is not related to Gaelic weddings, at least not yet.
There are three main locational hints in the consonant shapes. The plosives all have a vertically oriented form, the voiced plosives having their “weight” at the bottom. The nasals (and the other consonants) have a horizontally oriented form. The lateral [l] is derived from [n].
The other consonant shapes have various semi-regular alterations to account for different articulation methods. The affricates have the [t] form planted within. The semivowels are derived in a similar way to [l].
Vowels feature diacritics hovering above a rounded or open carrier. The carriers comprise only one bowl, unlike the non-plosives above. There are five points in the vowel-space, labeled here with the approximate phonemes. Three diphthongs are available in abbreviated form.
This is a transliteration of the beginning of Shakespeare’s sonnet 18, for comparison with versions of SIGIL etc etc.
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.
