Unde ( Whence, From where )
Venīre, Veniō ( Come, Approach )
Ahora sé por qué preferimos decir 'onde vienes?' que dónde xd
I said, Unde a venis?, but I'm told that it's wrong. Is that because "come from" is already implied in the verb "venis" = "(You) come from"?
As explained in the top comment on this page, "unde" means "from where".
As explained at the bottom of this page, "quo" means "to where".
