Questions & Answers about Vi är glada idag.
Why is there an "-a" at the end of glada?
Because the subject of the sentence, vi (we), is plural. In Swedish, when you describe a plural subject (more than one person or thing), you must add an -a to the end of the adjective.
If I wanted to say "I am happy today," would I still use glada?
No, you would use glad instead: Jag är glad idag. You only add the -a ending when describing a plural subject. Since jag (I) is singular, you drop the -a and just use the base form of the adjective.
In English, the verb changes from "am" or "is" to "are" for plurals. Why doesn't är change here?
Swedish verbs are incredibly friendly to learners! Unlike English, Swedish verbs never change their form based on who is doing the action. Whether the subject is singular or plural, the present tense verb stays exactly the same: jag är (I am), han är (he is), and vi är (we are).
I sometimes see "today" written as i dag with a space. Which one is correct?
Both are perfectly correct! You can write it as a single word (idag) or as two words (i dag). They mean the exact same thing and are pronounced identically, so you can use whichever you prefer.
