Prolagus "Da" literally means "from", but in this case it's more like "by" in "all by myself". Apr 11, 2010
PossibleUnderscore Does da have a separate meaning? Or does it just add to solo?
The first definition (according to the American Heritage Dictionary) is 'without companions; lone'. You could be in a room chock full of people and not have a single companion.
And even if you did, but had no connection with them you are still in a sense, alone and may very well be lonely. Apr 11, 2010
Prolagus I can see a difference between alone (being by yourself) and lonely (feeling far from those you love, or not having anyone). In Italian, I would use solo for the former and da solo for the latter. Apr 10, 2010
agatehinge To me lonely has a sense of yearning while alone does not. Apr 10, 2010
ruzuzu "I was never lonely... neither when I was alone, nor with others. But I would have liked to be alone at last. Loneliness means I'm finally whole. Now I can say it... as tonight I'm at last alone."
