Aquarium → It is formed from "aqua" (from Latin, meaning water) and "-arium" (from Latin, meaning a place for). The word "aquarium" refers to a place for water, specifically a container for aquatic life.
Think of 'water' ('aqua') and a 'place for' ('-arium') to remember that an aquarium is a place for aquatic creatures.
