However, the phrase "you speak German now" doesn't translate directly into a natural German phrase. It's a bit clunky.
Here are a few ways to express the idea of someone speaking German now in German:
* "Du sprichst jetzt Deutsch." (You speak German now.) This is a literal translation and the most common way to say it.
* "Jetzt sprichst du Deutsch." (Now you speak German.) This emphasizes the action happening in the present.
* "Du kannst jetzt Deutsch sprechen." (You can speak German now.) This focuses on the ability to speak German.
The best choice depends on the context and what you want to emphasize.
