Learn Portuguese (Portugal): Ela é uma pessoa apressada; aparenta nunca ter tempo livre. - She is a hasty person; she appears to never have free time.

This sentence highlights exactly how adjectives change meaning depending on the verb! While estar apressado means "to be in a hurry" (a temporary state), ser apressado means "to be a hasty person" (a permanent character trait). The inclusion of uma pessoa further locks in the use of ser, as it defines her underlying nature.

Could I use parece instead of aparenta in this sentence?

Yes, parece nunca ter would be perfectly natural and means the same thing. The verb aparentar is a slightly more formal or descriptive way to say "to give the impression of" or "to appear." It is excellent vocabulary to use at the B2 level to add variety beyond the basic verb parecer.

Why is the negative word nunca placed before the infinitive ter?

In Portuguese, negative adverbs like nunca, não, and jamais naturally attract to the position immediately before the verb they modify. This placement rule applies even when the verb is in its uninflected infinitive form, so saying ter nunca would sound entirely unnatural.

Why isn't the verb ter conjugated since it clearly refers to ela?
