Ruidososísimo or ruidísimo

Question

The third example above is written "Los conciertos de la calle son ruidosísimos."

If so, it seems to violate the rule of taking the masculin form and replacing the "o" with "ísimo".

If not, is it a typo?

Accepted Answer

Hola Tony
The use of "ruidosísimos" in the sentence "Los conciertos de la calle son ruidosísimos" is correct and not a typo. In Spanish, when an adjective ends in a vowel, like "ruidoso" (noisy), and you want to express the superlative, you typically follow the pattern of taking the masculine form and replacing the ending "o" with "ísimo".
So, "ruidosísimos" is the superlative form of "ruidoso", indicating an extremely high level of noise. This construction is consistent with the rule you mentioned and is appropriate in this context.
