[Rick392366]

How would you say "Is Tini's professor known by children"?

Apakah profesornya Tini dikenal oleh anak-anak?

'-nya' is attached to the noun to show the possessive form (Tini's profesor).

[Allverdizade]

cool, thank you :)

[TeisDraiby]

Could this translate as "Do the children know professor Tini?"?
That would sound more natural to me.

[ChristianH559404]

No. That would be "Apakah anak-anak kenal profesor Tini?"

To be even more correct/formal, the meng- form of "kenal", "mengenal" should be used.

Note that "kenal" means to know in the sense having a certain level of aquaintance with someone or experience/exposure with/to something. "Tahu" should be used instead if you mean merely knowing who someone/something is.

This sentence doesn't make any sense

[WillRobins645796]

I agree, the English translation is unnatural.

[SimonDyett]

More natural would be "Is professor Tini known by his/her children?"

[WillRobins645796]

So, Tini is now a professor. She is called Professor Tini. What abysmal English!!
