da solo

Italian

Literally, “as alone”.

by oneself
- 1943, Antoine de Saint-Exupéry, Il Piccolo Principe [The Little Prince], page 3:
  I grandi non capiscono mai niente da soli e i bambini si stancano a spiegargli tutto ogni volta.
  Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.
