How would you call this conjunctive in vadamus… Deliberative? I guess so
Inasmuch as Russian is already used in this topic, I would add explanation in Spanish taken from “El latin enseñado como lengua viva” (Hernandez, 1916). Particulary, lessons XXXVII (declensions) and LVI (adverbs of place):
- quo - a donde, ¿what is the final destination?
answer: in/ad + ACC - qua - por donde ¿whereby? ¿by which way?
answer: per + ACC
If you can read French see also Ernout Thomas Syntaxe latine on the contamination of meanings of ubi and quo.
