Learn German: Der Saft ist orange. - The juice is orange.

In German, only nouns are always capitalized. Here, orange is an adjective describing the color of the juice, so it is written in lowercase. If you were talking about the fruit (the orange), it would be a noun and capitalized as die Orange.

Why doesn't orange have an adjective ending here?

Because it comes directly after the verb ist instead of right before a noun. In German, adjectives only take special endings when they are placed directly in front of the noun they describe.

How do you pronounce orange in German?

Because it is a loanword, it sounds similar to the French pronunciation. The 'g' sounds like the 's' in the English word 'measure,' and it ends with a soft 'uh' sound instead of a silent 'e'.

Is there a trick to remember that Saft is masculine (der)?

There isn't a perfect rule, but many everyday drinks in German are masculine, such as der Kaffee (coffee), der Tee (tea), and der Wein (wine). Just remember the common exceptions: das Wasser (water) is neuter and die Milch (milk) is feminine.
