How to say "conservatory" in Japanese

• 温室おんしつJLPT N2approx.Common
  nounThe everyday word for the architectural sense: a glass building where plants are grown, a greenhouse. Use it for 'conservatory' meaning a structure, not a music school.
  私は温室おんしつでランを栽培さいばいしている。↗

  I grow orchids in my greenhouse.
• 音楽院おんがくいん
  nounA less common word for the institution sense: a school where music is taught, a conservatory or music academy. Use it when 'conservatory' means a place of musical education, not a glass building.
• コンサバトリー
  nounA katakana loanword for the architectural sense of 'conservatory' — a glass building or room for plants — rather than the music-school sense. It is a less common alternative to the everyday 温室.
• コンセルヴァトワール
  nounA loanword from French 'conservatoire', denoting a music conservatory. It carries a Continental flavor and, like 音楽院, refers to the institution where music is taught, not a glass building.
• 音楽学校おんがくがっこう
  nounLiterally 'music school': the plain word for an institution where music is taught. It can render 'conservatory' whenever 'music school' would fit the context just as well.

For a glass building for plants use the common 温室 (or the loanword 「コンサバトリー」); for a school of music choose 音楽院 or 音楽学校, with 「コンセルヴァトワール」 as the French-flavored loanword.
