o animal → os animais

animal → animals.

o pão → os pães

bread → loaves of bread.

💡

The -ão plurals are the trickiest. Nouns in -ção, -são, -zão predictably take -ões. The -ãos and -ães forms (irmão, pão, cão) must be memorised individually.

From a PortuStories Story

Os cães dos vizinhos latiam enquanto os pães arrefeciam na janela.

The neighbours' dogs were barking while the loaves of bread cooled on the window sill.
