vacuum
Space without matter
A vacuum is a space entirely devoid of matter—or more practically, a space with much less air pressure than the surrounding atmosphere.
Nature abhors a vacuum, filling empty spaces.
The word extends to any void or emptiness: His death left a vacuum in her life.
A vacuum cleaner (or just vacuum) removes dirt by suction; to vacuum is to clean with one.
In vacuum-packed goods, air has been removed to preserve freshness.
