A room with glass walls and roof for growing plants, or a school specializing in music or other arts.
From Latin conservare meaning 'to keep, preserve', from com- meaning 'together' and servare meaning 'to watch, keep safe'. Originally (16th century) meant any place for preservation, evolving to describe glass structures for protecting plants (17th century) and later schools for preserving and cultivating artistic traditions (18th century).
The dual meaning of conservatory - plant greenhouse and music school - beautifully captures the concept of nurturing growth in controlled environments. Both meanings share the idea of providing ideal conditions for delicate things (plants or artistic talents) to flourish under careful cultivation.
