In plain English: A vase is an open container used for holding flowers to decorate a room.
"She placed her favorite flowers in the tall green vase on the dining table."
Usage: A vase is specifically designed to hold cut flowers rather than potted plants that have their own soil and roots. While often made of glass or ceramic, the term applies to any rigid container with an opening wide enough to accommodate stems.
The word "vase" entered English via Middle French and originally came from the Latin vās, which simply meant a container or vessel. It is considered a doublet with the older English word "vas," sharing the same root but arriving through different linguistic paths.
