Questions & Answers about Lektionen slutar om en timme.
Why is the verb slutar in the present tense if the lesson is ending in the future?
In Swedish, you can often use the present tense to talk about the future as long as you include a time phrase that makes it clear. Here, the phrase om en timme (in an hour) tells us this happens in the future, so the present tense slutar works perfectly.
Doesn't om usually mean "about" or "if"? Why is it used here to mean "in"?
You're right that om often means "about" or "if" in other contexts. But when talking about a specific amount of time in the future, om translates to "in" or "from now". So, om en timme means "in an hour".
How do I know when to use timme instead of klocka?
Use timme when you are talking about a duration or a length of time (like "an hour"). Use klocka when talking about the physical object (a clock or watch) or the time of day on the clock (like in the phrase klockan tre for "three o'clock").
Why is it lektionen and not just lektion?
Lektionen is the definite form, meaning "the lesson". Since lektion is an en-word, you simply add -en to the end to change it from "a lesson" to "the lesson".
