Versare vs. rovesciare
When talking about spilling liquids by accident in Italian, the verbs rovesciare and versare are both commonly used, but they create slightly different mental images. The main difference lies in the cause of the accident: versare focuses on the liquid itself escaping or dripping, while rovesciare emphasizes the physical overturning or knocking over of the container that holds the liquid.
Versare
The verb versare primarily means to pour, but in the context of an accident, it translates to spilling a liquid. This word focuses on the actual liquid leaving its intended place, splashing, or overflowing, much like an accidental pour, without necessarily implying that the container was completely knocked over.

(I spilled some wine on the new tablecloth.)

Rovesciare
The verb rovesciare literally means to overturn, to flip over, or to knock down. When used to mean spilling a liquid, it specifically indicates that a container was tipped over or knocked down, resulting in a clumsy and often messy spill of its contents.

Summary
To summarize, use versare when you want to talk about the liquid itself dropping or splashing out of bounds. Use rovesciare when the spill is the direct result of knocking over, tipping, or overturning the physical container holding the liquid.
