"Ten hoch je dost silný."

[Essah_]

can "ten" not be interpreted as "this" or "that" as well?

[kacenka9]

Not really. TEN is just a determinant that it is a certain, known boy. In absence of articles, Czech retorts to pronouns. TEN could be there, that one. When something is THIS, it is right here, i am pointing at it, it is close. In Czech that would be TENTO or TENHLE boy.

However, we do accept "that" and it is a hint for this sentence.

Do you mean "fat enough" for something? "dostatečně tlustý"?

Theoretically yes, you could say "Ten hoch je dost tlustý.". However, I would prefer to say "Ten hoch je tlustý dost." to avoid confusion. Or use "dostatečně" instead of "dost".

"Ten hoch je dost tlustý." will be normally understood as "The boy is quite fat.".

If you are asking: Is "The boy is fat enough." a good translation of "Ten hoch je dost tlustý.", then I say NO, it is not. Because the meaning is normally: "The boy is quite/rather fat."
