Change the adjective below to a superlative by adding the appropriate ending (ísimo). altas

THIS IS THE BEST ANSWER 👇

The right answer is altisimas.

The word altas (meaning high) is used in the feminine, plural form. The feminine plural form is de alto. In order to form the superlative, we only need to add -isimo. But since it’s feminine, we should add add – isima. But since it is plural, we need to make additives to make -isimas.
