Even the real Lemonade in Europe is fizzy, so it actually is closer to Sprite than you’d think.

Obviously Spite isn’t really lemonade it’s soda, but that’s also not really a word that exists in Europe. It’s known about and it’s understood especially in more recent times, but historically it’s not really a word you’d commonly use.

So because Lemonade is sparkling, and the word soda isn’t really used, you can kind of see how people would then say well Sprite is Lemonade.
