Cola
In short
A carbonated soft drink flavoured with vanilla, cinnamon, and citrus oils. It is traditionally named after the kola nut, which provides caffeine.
In plain words
It is a fizzy, sweet drink often sold in cans or bottles. Most versions use sugar or artificial sweeteners for taste and contain caffeine to give a small energy boost.
A simple example
A person might order a glass of cola with ice and a slice of lemon at a restaurant.
Why it matters
It is one of the most popular beverage types in the world. Major brands have created a massive global market for flavoured soft drinks.
Easy to mix up
Do not confuse cola with coffee, as both contain caffeine but have very different flavours and ingredients.
