remove all the contents of (a container)

we empty the till at closing time

pockets were emptied of loose change

a bottle or glass left empty of its contents

the barman collected the empties

containing nothing; not filled or occupied

she put down her empty cup

the room was empty of furniture

(of words or a gesture) lacking meaning or sincerity

their promises were empty words

having no value or purpose

her life felt empty and meaningless
