Here's a breakdown:
* "Nu" is not a word in Spanish. It might be a typo for "no."
* "Nuevo" means "new" in Spanish.
* "Sol" means "sun" in Spanish.
Possible interpretations:
* "No nuevo sol": This means "not new sun," which could be interpreted as referring to something that isn't new or isn't about the sun.
* "Nuevo sol": This means "new sun," which could refer to a sunrise or something that is new and bright like the sun.
Without more context, it's impossible to say for sure what "nu nuevo sol" was meant to convey.
