Questions & Answers about Ella estará en casa ahora; las luces están encendidas.
In Spanish, the simple future (e.g. estará) is often used to express probability or supposition about the present, not just future time.
- Ella estará en casa ahora ≈ She is probably at home now / She must be at home now
- Literal future meaning: She will be at home (later) – but in this context, that’s not the intended sense.
This use is called “futuro de probabilidad” or “futuro de conjetura”. It’s very common and natural in Spanish, especially when the speaker is guessing or inferring something based on evidence (here, the lights being on).
So the future form estará here doesn’t refer to time, but to the speaker’s degree of certainty.
