Philippine English is not American English or British English.
Philippine English has a Filipino accent, and its expressions and usages are peculiar to the Philippines.
Even highly-educated Filipinos speak with a Filipino accent.
I have spoken with dozens or even hundreds of cultured Filipinos, and I found that their English is full of mistakes.
Filipino-accented English has faults, especially in pronunciations, prepositions (equivalent to te, ni, wo, ha in Japanese language),
nouns in the plural, auxiliary verbs and countable nouns.
In addition, numerals and genders.
The reason is easily explained. Their language does not have the same grammatical rules as real English.
In actuality, they speak Filipino-accented English with their own grammar and pronunciation.
Although several millions of Filipinos can communicate with each other without difficulties in their English, it is not American English.
