蒸留

1. Origins, structure, and basic meaning

• Structure: 蒸留 (reading じょうりゅう) is a noun and suru-verb for distillation: heating a liquid, then cooling its vapor to separate or purify components.
• Basic usage: It is used for collecting salt-free water from seawater or extracting fragrance material from petals.

2. Common pitfalls and similar expressions

• More than boiling
  • 蒸留 includes condensing and collecting the vapor after heating; boiling alone does not complete the process.
• Input and result
  • The source material takes を, as in 海水を蒸留する, and the recovered water or aromatic component is the result.
