"Get" or "fetch" or "bring" might be more common that "gather."
Yes agree. 'Gather' sounds weird. Although we do use gather + up for other objects, e.g. 'gather up your clothes'
yes to all of those suggestions, and also 'collect', but not 'gather' in this particular instance.
it's a fine distinction, admittedly, but for plates, no...
"Ambilkan sepuluh piring dari sana"
I agree with the comments regarding 'gather', and add that 'dishes' is marked incorrect. Is piring a plate in the generic sense such as a piece of flat metal?
Why not "Get ten plates from there."???
