"Who is there?"
Translation:Kiu estas tie?
The mobile version has done a crap job teaching me the difference between Tiu, Tio and Tie. Can someone explain. I'm so confused. Think I'm going to go search online.
Well, nine months late, here's my explanation....
tie - "there"
tiu - means "that" or "that person" and is used before a noun, or in answers to "kiu" ("who" or "which").
tio - means "that". It cannot be used before a noun. It answers "kio" (what).
- Tio estas pomo - that is an apple.
- Tiu pomo estas verda - that apple is green,
