Learn Dutch: Jij komt toch ook? - You are coming too, right?

Both jij and je mean 'you', but jij is used for emphasis. The speaker is specifically focusing on you to make sure that you, out of everyone else, are going to be there.

This is a question, so why doesn't the verb come first like in Kom jij...?

You can absolutely ask Kom jij? (Are you coming?). However, this sentence uses a normal statement word order (Jij komt...) and turns it into a question by adding toch at the end. It is just like saying 'You are coming, right?' instead of 'Are you coming?'.

What exactly does the word toch do in this sentence?

Toch is a very common Dutch filler word. Here, it is used to ask for confirmation, exactly like adding 'right?' or 'aren't you?' to the end of an English sentence. The speaker expects or hopes that you are coming.

How do toch and ook work together here?

Ook means 'also' or 'too'. By putting them together as toch ook, the speaker is asking for confirmation that you are doing the same thing as someone else. Literally, it feels like 'You are coming too, right?'
