uraniti

1. to get up early
   Danas sam uranio da bih stigao na prvi voz. — I got up early today to catch the first train.
2. to arrive too early; to be early
   Uranili smo pola sata, pa smo čekali ispred. — We were half an hour early, so we waited outside.
   Opa, uranio si danas! — Wow, you're early today!

The imperfective counterpart is uranjivati (rare). The verb raniti corresponds to the meaning 'to get up early' alone.
