Singleton Consonants

The phonex expression for singleton consonants has four parts:

1. Standalone consonants

(?<^\s?)(\c)$

1. Initial singleton consonants

(?<^\s?)(\c)(?>\v)

1. Medial singleton consonants

(?<\v\s?)(\c)(?>\s?\v)

1. Final singleton consonants

(?<\v)(\c)$

Use the double pipe (i.e., ||) operator to combine the expressions:

(?<^\s?)(\c)$ || (?<^\s?)(\c)(?>\v) || (?<\v\s?)(\c)(?>\s?\v) || (?<\v)(\c)$

1. Standalone onsets including onsets of empty headed syllables.

(?<^\s?)(\c:sctype("Onset|OEHS"))$

1. All other singleton onsets

(?<\S)(\c:O)(?>\v)

Combined:

(?<^\s?)(\c:sctype("Onset|OEHS"))$ || (?<\S)(\c:O)(?>\v)

1. Standalone codas

(?<^\s?)(\c:C)$

1. All other singleton codas

(?<\v)(\c:C)(?>\S)

Combined:

(?<^\s?)(\c:C)$ || (?<\v)(\c:C)(?>\S)
