Exactly why teaching tenses and "passive voice" doesn't work because there are no Tagalog equivalent. And that learners should accept that Tagalog has different focuses/triggers instead of passive/active voice (if you dig in previous threads, many learners insist that the -in- form is "passive) and that Ma- like taga- have more than one use. Like other languages, it takes time to get used to it. After all, like what others have said, language isn't a mathematical equation. While there are patters, many deviations occur. And these deviations don't really have "logical" explanation. It is what it is. After all there's no logical explanation behind good, better, best but pretty, prettier, prettiest. It is what it is.
Trying to question why Ma-tutulog ako, but not Ma-gaganda ako won't really help learners. That's really like questioning why is it good, better, best instead of good, gooder, goodest unlike pretty, prettier, prettiest. It would be easier if they will get familiar with and when to use this kind of Ma- and that kind of Ma-
Or like questioning why are there mag- verbs and -um- verbs that learners have to be familiar with. Why not just use mag- for all to make it "easier"? Well, whether they like it or not, mag- and -um- is how the language works. You adjust to language and not the language adjusting to you.
Take the language rules as it is because questioning "irregularities" , and why unfamiliar concepts exist won't help learning.
Why are there two uses ma-? Why are there two uses of taga-. Why not just change taga- + place to something not taga-?
One can explain what stative verbs in Tagalog are for years. But in the end, learners will have to memorize and be familiar with Ma- + stative verb that are conjugation with affixes that aren't Ma- when conjugating for aspect and focus. In short, they have to accept which verbs are used as Ma- as in matulog ang ma- as in maganda. Just as much as accepting taga- is used for tagaprobinsya and taga- as tagaluto. Asking by both are "taga-" doesn't help with learning.
