Call like shout to me to come or call like call on the phone?
Call on the phone.
I'll call you! meaning 'shout to you to come' would use accusative Zavolám tě
What is the difference between "ti" and "tobě" ?
Why can't we say "Já tobě zavolám" ?
Ti is unstressed and clitic (placed second position), tobě is stressed and cannot be used in the second position (unless it is the final position and it is stressed).
What translation: I'll give you a ring?
If you are implying we are missing it, you should use the report butron.
