Question: Syntax question:

Seems standard.Hindi ko siya lola is correct.

@Diegocorry edit: not sure of my translation there

@PinoyTaj, @AMBoy Thanks for your responses. "I am not his/her grandmother," doesn't seem to make sense in the context. Here is more; the speaker is a young boy: "Hindi ko siya lola, at hindi siya lola ng mga kaibigan ko. Pero dahil matanda na siya at puti ang buhok, 'lola' siya ng lahat ng bata sa aming kalye."
"I am not his/her grandmother," would mean a little boy is saying he is not an old woman's grandmother. I think I'm missing something. Any further thoughts?

@Diegocorry Where did you get this from?

@PinoyTaj It’s a story from Rosetta Stone.

@Diegocorry Explains everything lol

@PinoyTaj Yeah. I went through the RS course a few years ago, and was underwhelmed to say the least!

I think the text is whacky, I think it's missing some angs:"Hindi siya ang lola ko, at hindi siya ang lola ng mga kaibigan ko. Pero dahil matanda na siya at puti ang buhok niya, 'lola' siya ang lahat ng bata sa aming kalye."Even after , feels weird.

Hindi ko siya lola. -> she is not my grandmotherHindi siya ANG/YUNG lola ko -> She is not my grandmotherHindi lola ko siya. -> No, she is my grandmotherTo say this: . "I am not his/her grandmother,"Hindi ako ang lola niya

Syntax correct."Hindi ko siya lola" is literally "she is not a grandmother(/grand aunt) of mine." but is usually meant and understood as "she is not my grandmother.""at hindi siya lola ng mga kaibigan ko."
> "and she is not a grandmother(/grand aunt) of my friends'.""Pero dahil matanda na siya at puti ang buhok, 'lola' siya ng lahat ng bata sa aming kalye."
> "But because she is old and her hair is gray, she is a "grandma" for all the children in our street."

"Hindi siya lola ko."
Passable as an IM or chat, or informal talk. Do not speak or write this way unless you have reached advanced level Tagalog. "Hindi lola ko siya." Ungrammatical.
