daarbij

While both can mean 'next to it' or 'in addition to it,' 'daarbij' often implies a more abstract addition or inclusion, like adding a point to an argument. 'Ernaast' is typically more literal, referring to physical proximity.

Example:
Ik wil daar een huis kopen, en daarbij zoek ik een goede baan. (I want to buy a house there, and in addition to that, I'm looking for a good job.)
Zet de stoel ernaast. (Put the chair next to it.)

Yes, absolutely! 'Daarbij' can indicate simultaneity, meaning something happens concurrently with something else.

Example:
Hij zong een lied, en daarbij speelde hij gitaar. (He sang a song, and at the same time he played guitar.)

'Daarbij' is quite neutral in formality. You'll hear and read it in both formal and informal contexts. It's a standard and useful word.

It depends on the context!

For 'in addition to that,' you might use:
Bovendien (moreover)
Ook (also)
Verder (further/moreover)

For 'at the same time,' you could use:
Tegelijkertijd (simultaneously)
Ondertussen (meanwhile)

However, 'daarbij' often has a subtle nuance that these alternatives don't fully capture, especially when referring to something being 'included in' or 'part of' something else.

'Daarbij' is a more general or abstract version of 'erbij'. 'Erbij' often refers to something being physically 'with it' or 'added to it' in a more concrete sense. 'Daarbij' can be more about a conceptual addition.

Example:
Ik wil melk erbij. (I want milk with it.) - Physical addition.
Ik heb al een huis, en daarbij ook een auto. (I already have a house, and in addition to that, also a car.) - Conceptual addition.

Yes, you can! Starting a sentence with 'daarbij' is perfectly natural, especially when you're adding information or a related thought to a previous statement.

Example:
De les was interessant. Daarbij was de docent ook erg aardig. (The lesson was interesting. In addition to that, the teacher was also very kind.)

Almost always, yes. 'Daarbij' is a pronominal adverb, meaning it refers back to something already established in the conversation or text. It links new information to previous information. If there's no clear reference, it can sound out of place.

'Daarbij' is a combination of 'daar' (there/that) and 'bij' (at/with). So, you can think of it literally as 'at that' or 'with that'. This helps explain its various meanings of 'in addition to that' or 'at the same time as that'.

It's less common, but yes, it can be used, usually to refer back to something someone else said.

Example:
A: Ik ga morgen naar de bioscoop. (I'm going to the cinema tomorrow.)
B: En daarbij, wat ga je daarna doen? (And in addition to that, what are you going to do afterwards?)

It's not as frequent as in statements, but grammatically possible.

While both contain 'daar'/'there' and 'bij'/'by', 'daarbij' generally does not translate directly to 'thereby'. 'Thereby' often indicates a result or consequence (e.g., 'thereby causing'), whereas 'daarbij' focuses more on addition, inclusion, or simultaneity.

For 'thereby,' you might use words like 'waardoor' (whereby/causing) or 'daardoor' (thereby/because of that) in Dutch.
