Additional Details:
Well, thank u all for those answers ^^.
So, let's sum up! ;-)
I take it as granted that, as Romulus said, "Para siyang oso kung maglakad" literally means: "He looks like a bear when he walks."
Then perhap's i can just say:
Para siyang oso" to mean "He looks like a bear"? **(1)
And maybe:
Para akong oso "I look like a bear"?? **(2)
Now, the other set of examples...
First part:
> Either u use the regular verb-subject order, or the "inverted order" (in which case u need to add "ay")
> Either u use lumalakad or naglalakad for the present tense of "lakad".
That makes 2x2 logical possibilities:
Siya ay (Siya'y) lumalakad/naglalakad
Lumalakad/naglalakad siya
I guess it is so independently of the added element, coz in each case, you can add "na parang uso" ("like a bear"). Is it right? **(3)
Second part:
Here also there seem to be 2x2 possibilities (at least, but it s enough! ^^):
na parang isang oso
na parang oso
kagaya ng isang oso
kagaya ng oso
I ll assume that "na para" and "kayaga" are equivalent and mean "like" (and both need an additional "ng").
Now, what does "isang" mean? What is the difference between "... isang oso" and "... oso"?? **(4)
It s highly possible that some of my assumptions are wrong, but if not, I still have additional questions (with ** and a number).
Mind for some more help? ;-)
