This is the 18th most frequent Swedish word.
jag
"I."
The word 'jag' functions as the subject pronoun, meaning 'I' in this sentence.
Jag läser en bok.
I am reading a book.
Here, 'jag' once again acts as the subject pronoun of the sentence, denoting the person's identity performing the action of eating.
Jag äter frukost varje morgon.
I eat breakfast every morning.
In this context, 'jag' is used twice as the subject pronoun for different clauses, showing its usage in more complex sentence structures.
