Basic translation and structure

The direct translation of the English sentence The fish are colorful is Os peixes são coloridos in Brazilian Portuguese. This sentence uses a plural subject, the verb ser to indicate a general characteristic, and an adjective that agrees in number and gender with the noun.

Breakdown of the sentence:

Os = the (plural masculine definite article)

Peixes = fish (plural form of peixe)

São = are (third-person plural of ser)

Coloridos = colorful, plural masculine form of the adjective colorido

Why use ser and adjective agreement
