odozdo

1. from below; from underneath
   Odozdo se čula muzika iz kafića. — Music from the café could be heard from below.
   Kutija je mokra odozdo. — The box is wet underneath.
2. (of society, politics) from below; from the grassroots
   Prave promene moraju doći odozdo. — Real change has to come from below.

Do not confuse with dole 'below': odozdo means 'from below' or 'on the underside', while dole generally just indicates a lower location (where?).
