General understanding:
* Tu sais quoi? (formal and informal) - This is the most common and direct translation, meaning "you know what?"
* Tu vois? (formal and informal) - This means "you see?" and implies that the listener understands what you're referring to.
Adding emphasis or surprise:
* Tu sais ce que c'est? (formal and informal) - This means "you know what this is?" and emphasizes a specific object or concept.
* Tu sais quoi ? (formal and informal) - This is the same as the first translation but adds a rising intonation to emphasize surprise or a sense of revelation.
Other options:
* Tu comprends? (formal and informal) - This means "Do you understand?" and can be used when you're explaining something.
* T'as capté? (informal) - This means "Did you get it?" and is a more casual way of asking if the listener understands.
The best translation will depend on the specific context and the tone you want to convey.
