The indigenous characters were recorded as
culit by the early 17th and 18th century Spanish lexicographers (Benavente, 1699 and Bergaño, 1732). This served as inspiration for the name "Kulitan" which was recently coined to refer to the modern writing system. The ordinary folks simply called them
Súlat Kapampángan to distinguish them from the
Latin script. Kulitan is made up of
Indûng Súlat, or the "progenitor" (literally "mother") characters, and the
Anak Súlat, or the "offspring" (literally "child") characters. The Indûng Súlat are the base characters with the unaltered inherent vowel sounds. They are the building blocks of Súlat Kapampángan. Indûng súlat gives birth to Anak Súlat or "offspring" characters whenever their inherent vowel sound has been altered by a ligature or a diacritical mark. The
siuálâ or vowels in Kulitan are usually written as
garlit or diacritical marks placed above or below an individual Indûng Súlat or "mother" character. Ligatures are also sometimes used to further lengthen these vowel sounds or represent the monophthongized diphthongs AI (E) and AU (O). A glyph with a diacritical mark or ligature attached to it is an Anak Súlat or "offspring" character. A consonant can lose its following vowel if written at the right side of the preceding consonant. The recital order of the Indûng Súlat characters are A, I, U, E, O, GA, KA, NGA, TA, DA, NA, LA, SA, MA, PA, BA. ==Direction of writing==
