I'M SO SORRY FOR THE LATE newsletter yall, I could have sworn I scheduled this already but it turns out I lost the whole thing... here we go (second time's the charm hehehe) 

Let's get right into this week's issue of Teugether! ☺️

  

omg this is SUCH a good and niche question, thank you for asking this!! 

So if we're talking translation, they both mean the same thing - which is "give me (this)" 

You would usually use this when you're ordering and just pointing at something on a menu or even like on a display - can be used at a shop/restaurant/cafe ! 

BUTTT the contextual difference is that you would use 이걸로 주세요 when you're choosing between different options (like multiple flavors of ice-cream) while the former is just "give me this" 

I'd say the english equivilent would be something like:

이거 주세요 - Please give me this 

이걸로 주세요 - I'll take this ONE 

The difference is really small but definitely exists! <3
