Learn Portuguese (Portugal): Os gatos, que dormem muito, adoram o sol.

In Portuguese, when you talk about a whole category or make a general statement—like cats in general—you must use the definite article (o, a, os, as). In English, we drop the "the" for generalizations, but dropping it here would sound unnatural in Portuguese.

The word que translates to "which" here. Could it also mean "who" if we were talking about people?

Yes! The word que is a very versatile relative pronoun. It connects phrases and can mean "that," "which," or "who" depending on the context. If the sentence were about boys ("The boys, who sleep a lot..."), you would still use que (Os rapazes, que dormem muito...).

Why does the sentence use adoram for "love" instead of a form of the verb amar?

In Portuguese, adorar is the standard way to say you "love" a thing, an activity, or a place (like the sun, food, or a hobby). The verb amar is much stronger and is typically reserved for deep, romantic love or profound affection for people.

Both dormem and adoram end in -m. Do I pronounce it like a hard English "m"?
