Questions & Answers about Cuando llegues a la base, ellos ya habrán puesto los paneles solares en la cúpula.
How does habrán puesto translate to "will have put"?
This is the future perfect tense, which is the focus of your current lesson! You form it by combining the future tense of the helper verb haber (here, habrán for "they will have") with a past participle. In this case, we use puesto, which is the irregular past participle of poner (to put).
Why is it cuando llegues (subjunctive) instead of cuando llegas?
In Spanish, you must use the subjunctive mood after cuando when you are talking about an event that hasn't happened yet. Since your arrival at the base is in the future, the subjunctive llegues is required. If this were a routine statement like "whenever you arrive", you would use the normal present tense llegas.
In English we say "will already have put". Can I put ya between habrán and puesto?
Why is the plural of solar spelled solares?
