Questions & Answers about Una chispa habrá causado un cortocircuito.
Why is the future perfect (habrá causado) used to translate a past action ("must have caused")?
This is a special use of the future tense called the future of probability. In Spanish, you can use the future perfect to make a strong guess or state an assumption about something that already happened. Even though the spark happened in the past, your deduction is happening right now. English usually expresses this same idea with the phrase "must have".
Could I say debe haber causado instead of habrá causado here?
Yes, absolutely! Saying una chispa debe haber causado un cortocircuito means the exact same thing. Using the future perfect (habrá causado) is just a very common and natural-sounding alternative for expressing that same past probability.
If habrá causado literally means "will have caused", how do I know it means "must have caused" here?
Context is everything. If the sentence had a future time marker like para mañana (by tomorrow), it would mean "will have caused." But without a future time marker, if you are looking at a broken machine or a blackout, it is clearly a deduction about what just happened in the recent past to cause the problem.
Is cortocircuito a compound word, and how does its gender work?
