Questions & Answers about Kan du hjälpa mig på torsdag?
Why does the sentence use hjälpa instead of the present tense hjälper?
Because it follows the helper verb kan (can). Just like in English, when you use a helper verb, the main verb stays in its base or dictionary form (the infinitive). So it is kan du hjälpa (can you help), not kan du hjälper.
I've heard people say something that sounds like mej. Is that the word mig?
Yes, exactly! Even though it is spelled mig, it is almost always pronounced like mej in everyday spoken Swedish. You might even see it spelled as mej in very informal text messages.
Is it a typo that torsdag starts with a lowercase letter?
No, that is entirely correct! Unlike English, Swedish does not capitalize the days of the week, months, or languages.
Does på torsdag mean "on Thursday" in general, or this upcoming Thursday?
Saying på torsdag means "on Thursday" referring to the upcoming Thursday. If you wanted to talk about a recurring habit, like "I work on Thursdays", you would add an -ar to make it plural: på torsdagar.
