Learn Spanish (Latin America): La chica distraída tendrá mucha prisa. - The distracted girl must be in a big hurry.

This sentence uses the future tense to express a guess or assumption about the present. This is often called the future of probability. While tendrá literally means "will have," in this context it translates to "she probably has" or "she must have."

Why does the Spanish sentence use tendrá (a form of to have) when the English translation says "must be"?

In English, you "are" in a hurry, but in Spanish, you "have" a hurry (tener prisa). This works just like tener hambre (to be hungry) or tener frío (to be cold). Because we are guessing that she is in a hurry right now, we use the future probability form of the verb tener.

Why use mucha instead of muy before prisa?

Because prisa is a noun meaning "hurry" or "rush," you need the adjective mucha (a lot of / much) to describe its amount. You only use muy (very) before adjectives and adverbs, never before nouns.

Why does distraída have an accent mark on the 'i'?

The word distraída has a sequence of two vowels: an open 'a' and a closed 'i'. To show that the spoken stress falls on the 'i' and breaks the vowels into two separate syllables instead of blending them together, the 'i' requires a written accent mark.
