The Vietnamese word "giát lò" translates to "grate" in English. It refers to the action of shredding food into smaller pieces by rubbing it against a rough surface, often using a kitchen tool called a grater.
In a more advanced context, "giát lò" can also refer to the action of grating non-food items in a metaphorical sense, such as grating one’s nerves (though this is less common).
While "giát lò" primarily means "to grate," it may also be used in some dialects or contexts to imply "to irritate" or "to bother," although this usage is less common.
