How to say "lemonade" in Japanese

• レモネード
  nounThe katakana loanword, so it sounds like the English word; it means the sweet lemon drink itself. A less common choice, but the form you see on cafe menus.
• レモン水レモンすい
  nounLiterally 'lemon water': lemon juice diluted with water, often sweetened. A less common word for lemonade, it suits homemade versions; it can also mean lemon-juice water that keeps cut fruit from browning.

Both are less common ways to say lemonade: 「レモネード」 is the direct loanword for the sweet lemon drink, while 「レモン水」 literally means lemon water, i.e. lemon juice diluted with water.
