Translation

薄める / 希釈する / 弱める

Meaning

Dilute means to make a liquid weaker or less concentrated by adding water or another liquid. The object is the strong liquid, not the liquid you add. The learner trap is confusing dilute with delude, which means deceive.

Examples

• この濃縮液は水で薄めてください。
  Dilute this concentrate with water.
• 看護師は薬を食塩水で希釈しました。
  The nurse diluted the medicine with saline.
