"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"
Is this skill about words ending with -an that aren't nouns?
