Here's why:
* Historical Usage: The spelling "Visaya" has been more widely used in English literature and academic publications.
* Pronunciation: The "Visaya" spelling reflects the pronunciation of the word more accurately, with the stress on the first syllable.
* Consistency: The spelling "Visaya" is consistent with the English spelling of other related terms like "Visayan" and "Visayan language."
However, it's important to note that "Bisaya" is the preferred spelling in the Cebuano language itself, which is the most widely spoken Visayan language.
Ultimately, the choice of spelling depends on the context and the target audience.
