Is there a latin root meaning for fog?

There isn't a single Latin root word specifically meaning "fog." However, the Latin word "nebula" (meaning "cloud" or "mist") is a close relative of the word "nebula" in English, which refers to a cloud of gas and dust in space.

While "nebula" itself isn't the exact root for "fog," it represents a related concept and shares a common linguistic origin.

Another relevant Latin word is "vapor", which means "steam" or "vapor." This could be considered a broader term that encompasses the concept of fog.

Therefore, while there isn't a singular Latin root directly translating to "fog," words like "nebula" and "vapor" offer similar concepts and share linguistic ancestry.
