Avete,
Recently I saw, included in an English poem by Browning, a stretch of Latin: salve tibi used as a way to greet someone else. Here in SVR and other places the norm is to have salve or salvete followed by a name in the vocative case.
However, tibi is clearly in the dative case. What do the other latinists here think? Can both be used, or dative case only, in which case we are greeting each other wrongly! (if it is true, I'm going to fetch me a rope and hang myself).
Additionally, Mus recently told me that in the Latin letters he's read, salve and vale not used. If it was used, it was probably rather informal.
I await your opinions.
Valete;
Draco
