I can understand why you’ve been confused since I haven’t posted yet what I think are the more apt descriptions of Tagalog and Bikol. I’ve prepared a draft already but I’ve been busy lately to review and make sure its not hastily done.

Well, I am actually not intending to teach Tagalog. Its not a language I am very fond of as it is eclipsed by Bikol in richness, and I normally go for languages that are more complex. Right now, I am very interested in Bikol, Itbayaten, Amis, Tongan, and Javanese among the Austronesian languages.

I just put Tagalog there so people who speak, undestand or study it would have an idea of how Bikol contrasts with it, though of course I want to be as accurate as possible in describing both. My aim is to create a conlang, and having an accurate description of Bikol grammar is just a preparation for my conlang. This conlang is mainly a mix of Austronesian, Salishan and Australian language characteristics.

Sorry to disappoint you if your looking for Tagalog materials. But you can check out my blog later if I’ve posted any grammar descriptions relating to Tagalog. Or since you’ve mentioned voice/focus, which I suppose is the more complex part of Philippine-type languages’ syntax like Tagalog, I will post something but I am not in a hurry to do so as my work and other hobbies eat a large part of my time. I’ve seen quite a few websites with good Tagalog materials, so maybe you can check those out. If you have any queries about Tagalog grammar, usage, etc, post it anywhere in my blog (preferrably the most relevant post/page) and I will endeavor to help you by posting the relevant topic. Dios mabalos asin magayagaya na pag-aadal!
