Questions & Answers about På tisdag är han ledig.
Why is it är han (is he) instead of han är (he is)?
Swedish uses the verb-second rule. Because this sentence starts with the time phrase På tisdag, the verb är must come next, pushing the subject han to the third position.
Does på tisdag mean every Tuesday or just this upcoming Tuesday?
It means this upcoming Tuesday. If you wanted to say on Tuesdays in general, you would use the plural form på tisdagar.
Can I use ledig to say that a coffee is free?
No. Ledig means free as in having time off from work, or a seat being available. If something costs zero money, you use the word gratis.
Why isn't the word tisdag capitalized?
In Swedish, days of the week, months, and languages are written with lowercase letters, unlike in English.
