Explanation.
Jerome Beers Thomas translation
For the common words of the different Filipino dialects I have adopted the orthography which in my various treatises on those dialects I have demonstrated to be the easiest, most rational and convenient. I should be inconsistent as to my own theories and convictions if I continued to follow the old form of spelling. For the benefit of those who are not familiar with the matter I will state that the consonants are pronounced as follows:
g always as in get.
h gutturalized aspirate.
k as in English.
w always as initial w in English, win, wan.
g̃ as ng in sing, hung, etc.
