Unde = where from
Ubi = where
Quo = where to
Unde doesn't work here?
Ubi = static location: Where are you? Ubi es?
Quo = motion toward: Where are you going? Quo vadis?
Unde = motion away: Where do you come from? Unde venis?
Thank you Rae.F
unde is 'from where', implies some movement. ubi is simply location.
e.g. unde venis -> "Where are you coming from?"
I tried the plural "you" but it wasn't accepted:
"Ubi vos agri sunt?"
Should this be considered correct also?
"Vos" is "you". You need "vostri", which is "your".
Ah! Thank you.
