n. a space entirely devoid of matter
n. (colloquial) a vacuum cleaner
vt. to clean with a vacuum cleaner
Derived from Latin vacuus (empty), the word vacuum entered English in the 16th century to describe a void space. The scientific sense (absence of matter) emerged later, while the colloquial use for the cleaning device dates to the early 20th century. The morpheme vacu- preserves its Latin root meaning "empty," and -um is a neuter noun suffix common in Latin loanwords.
