で

すみません、ちょっと。食事の準備で忙しいので。。。またあとで。

What is the meaning of で here?

 

[Angel Valis]

で here means "because of" or "due to". It admittedly sounds a bit awkward in English with two "because"-like elements. If you want, you could probably translate it to "with", therefore: "Since/because I'm busy with meal preparation...".

I didn't expect that . Thank you!
