Unknown to many foreigners, the original Philippine Alibata (alphabet) has no C, F, J, Q, V, X, and Z.
Patinig are the vowels while the Katinig are the consonants. However, the modern day “informal” Philippine alphabet now include the 7 English consonants.
By the way, the letter “J” was only invented in the 17th century. Accordingly, it was theorized by most bible scholars that the name “Joseph” and “Jesus” are not the original names of certain biblical figures.
