Question

what does vacuum mean in this sentence? guests will be here in five minutes, so wed better vacuum quickly! vacuum noun a space that is completely empty vacuum verb to clean with a device that sucks air

Explanation:

In the sentence "Guests will be here in five minutes, so we'd better vacuum quickly!", "vacuum" is used as a verb (since it's an action we need to do quickly before guests arrive). The verb definition of "vacuum" is "to clean with a device that sucks air", which fits the context of cleaning quickly before guests come. The noun definition (a space that is completely empty) doesn't fit here as we need an action word.

Answer:

vacuum verb to clean with a device that sucks air
