Learn Spanish (Spain): Ese paciente todavía no ha mejorado.

In Spanish, adverbs like todavía no (not yet) usually go before the verb. Unlike English, where "yet" often gets pushed to the very end of the sentence, Spanish prefers to put todavía no right before the verb phrase (ha mejorado).

Why are we using the Pretérito Perfecto (ha mejorado) in this sentence?

The Pretérito Perfecto (have/has + past participle) is used for past actions that still connect to the present. When you use todavía no, you are talking about an action that hasn't happened up to this exact present moment. That makes this tense a perfect match!

Could I just say todavía ha mejorado instead of todavía no ha mejorado?

No, because todavía by itself usually means "still." If you left out the no, it would sound like "still has improved," which doesn't make sense for what we are trying to say. To say "not yet," you must use the negative form todavía no.

I see ese paciente. Can a female patient be esa paciente?

Yes! The word paciente ends in -e, meaning the noun itself doesn't change for gender. To show whether the patient is male or female, you change the adjectives around it. Here, the masculine word ese (that) tells us this is a male patient. For a female patient, it would be esa paciente.
