"He turns toward her."

Translation: Lui si gira verso di lei.

[squaredomino]

Can anyone tell me why "gira" is preceded by "si"? And why "di" is necessary if "verso" means "towards"? This is the first time I've come across it, and I don't understand.

[siebolt]

girare + object = to turn something. "girarsi" = to turn (around) I turn = (io) mi giro. There are some prepositions which can be acompanied by "di" like "verso di", "senza di"
