Italian Word of the Day: Pietra (rock, stone)

The Italian word pietra (feminine, plural: pietre) can be translated as either rock or stone in English. It comes from the Greek word πέτρα (pétrē).

As you can see from the two examples below, pietra is used to talk about both the compact mass formed by natural mineral substances, as well as the smaller fragments that break off from that mass.

Questo pavimento è in pietra.

This floor is made of stone.


Il bambino ha lanciato una pietra alla finestra.

The boy threw a rock/stone at the window.


A good way of remembering the word pietra is to think of the English name Peter (or Pietro in Italian) which both mean stone.

Below are a few useful terms containing the word pietra:

  • pietra miliare = milestone
  • pietra preziosa = gemstone
  • pietra filosofale = philosopher’s stone
  • età della pietra = stone age
  • pietra tombale = tombstone
  • pietra a vista = exposed / natural stone

A famous quote from the Bible is Let him who is without sin cast the first stone. This translates as Chi è senza peccati scagli la prima pietra in Italian.

A synonym for pietra is sasso. There isn’t a clear distinction in many cases, except for specific terms such as pietra preziosa (you wouldn’t say sasso prezioso). Sasso is also more common for stones that have been smoothed by water.

La spiaggia è ricoperta di sassi.The beach is covered with stones.
