Learn Swedish: Fienden hinner inte nå skyddet. - The enemy does not have time to reach the cover.

The single Swedish verb hinner (from the infinitive hinna) means "to have enough time to do something" or "to make it on time". While English needs a whole phrase to express this concept, Swedish builds it into this one specific verb.

Since hinner means "have time to", shouldn't there be an att before nå?

No, the verb hinna works like an auxiliary (helping) verb in Swedish. Just like you say kan nå (can reach) or ska nå (will reach) without att, you simply say hinner nå (have time to reach) without it.

The dictionary form of "enemy" is fiende. Why is the definite form fienden and not fiendeen?

Fiende is an en-word. Normally, you add -en to the end of a word to make it definite, but if the noun already ends in an -e, you just add -n. This avoids creating an awkward double vowel.

Is skyddet related to the verb for "to protect"?

Yes! Skyddet means "the cover" or "the protection". It is the definite form of the noun ett skydd, which is directly related to the verb att skydda (to protect).
