Final answer:
A drink that is half coffee and half steamed milk is known as a Caffè Latte or Café au lait. The Latte combines espresso with steamed milk, while a Café au lait uses brewed coffee with milk.
Step-by-step explanation:
The two names for a drink that is half coffee and half steamed milk are Caffè Latte and Café au lait. These beverages are part of the wide range of coffee drinks enjoyed by many. A Caffè Latte typically consists of one-third espresso and two-thirds steamed milk, often topped with a small amount of foam, while a Café au lait, more common in French cafés and New Orleans's coffeehouses, is made with brewed coffee instead of espresso, with an equal amount of milk.
Apart from the half-and-half composition, coffee enthusiasts might add various ingredients like sugar, syrups, or even spices to customize their drinking experience. In this way, a simple cup of coffee or espresso turns into something unique to the drinker's tastes, illustrating the dissolving process as well as the cultural adaptability of coffee-based beverages.
