Baybayin is a Pre Spanish Filipino Script.
Here are names that starts with the letter A written in the Modern baybayin.
What makes it a modern baybayin.
Modern baybayin uses the vowel cancellation mark to take out the vowel.
Each character inherently comes with the vowel "A" other than the vowel themselves.
Here are the 17 characters written in the western alphabet.
A, BA, KA, DA/RA, E/I, GA, HA, LA, MA, NA NGA, O/U, PA, SA TA, WA, YA
Baybayin is syllabic so the characters represents a syllable.
It is written as its pronounced.
The SHA is written as SI YA
Broken down to the syllables
The Au sounds is A W hence A W RO RA
If you noticed, there's a kudlit at the bottom of the SA character, That kudlit makes the sound O/U hence the SU in A SU RA
There's no X in the Tagalog/Filipino Alphabet
So it can be written as what character sounds the closest.
The combination of the K and the S will work
A K (adding a vowel cancellation on the K) followed by the SE then L (also with the vowel cancellation mark.)
A K SE L
The character DA/RA is the same, so usually baybayin practitioners add the slash on the character to make it RA to distinguish the two character.
Alot of tagalog / Filipino word have the DA/RA inrterchangeable.
Padaan - Paraan means the same.
Would be written the same way.
Written the same way since its sounds the same.
