Questions & Answers about Escucho una sirena muy fuerte, debe de haber un choque.
Why is escucho translated as "I hear" instead of "I listen"? Shouldn't it be oigo?
I thought fuerte meant "strong." Does it mean "loud" here?
Exactly! When talking about sounds, voices, or volume in Spanish, you use fuerte for "loud." The sound is described as "strong" rather than using a separate word for loud.
How exactly does debe de haber mean "there must be"?
This sentence uses the structure deber de + infinitive to express a strong assumption or probability ("must"). Here, it is combined with haber, which is the infinitive form of hay ("there is" / "there are"). Put them together, and debe de haber means "there must be."
Could I just say debe haber without the de?
Strictly speaking, deber de is used for probability or guessing ("there is probably a crash"), while deber without the "de" is for obligation ("there is required to be a crash"). However, in everyday spoken Spanish, people often drop the de and just say debe haber for both meanings. Keeping the de here makes it perfectly clear that you are just making an assumption.
