why is almond milk or soy milk also called ''milk'' when almond and soy have no breasts?!

Even though, the commercially and commonly used milk is the lactation from the mammary glands (breasts) of animals, the solution derived from almond or soy or coconut or other nuts is also called milk. Because the derived solution has similar color, similar consistency and almost similar taste.

By addressing it as “milk” it makes it easy to globally understand what are the uses, benefits, characteristics and appearance without much explanation. Because it immediately draws a picture in everyone’s mind and makes it easily acceptable. Also, such derived milk is used similar to using regular milk or as a substitute in recipes which involve the use of regular milk.

For example, had almond milk named almond juice, it would appear something one wants to use in cocktails rather than in cookies.

Milk does not necessarily have to come from the mammary glands of an animal. Milk can also be used to describe a liquid substance similar in appearance to milk, such as coconut milk.

The word milk is used for these drinks as their intention is typically to replace animal milks in a persons diet. When someone thinks of juice, they tend to picture a sweet liquid.

I don't think juice quite describes it very well either, and frankly, people using these products usually use them as a milk replacement.
