What does the root word solu mean?

The root word "solu" comes from the Latin word "solvere," meaning "to loosen, to untie, to release, to dissolve, to pay."

It's important to note that "solu" is rarely used independently as a root word. It typically appears as part of a larger word, such as "solution" or "dissolute," where its meaning is embedded within the overall word's definition.
