Questions & Answers about Os cães e os gatos são animais bonitos.
How do you form the plural word animais?
Why is the plural of dog cães instead of "cãos"?
Why does the Portuguese sentence say Os cães e os gatos when the English translation just says "Dogs and cats"?
In Portuguese, when you talk about things as a general category (like dogs and cats in general), you must use the definite article (o, a, os, or as). So, to say "Dogs" generally, you have to say Os cães.
Why does bonitos come after animais, and why does it end in -os?
In Portuguese, adjectives (describing words) usually come after the noun they describe. Because animais is a masculine plural noun, the adjective bonito must also change to its masculine plural form, bonitos, to match.
