Here are some examples of how it's used:
* Wewe ni mrembo. (You are beautiful.)
* Unaitwa nani? (What is your name?) Wewe: (You: followed by your name.)
* Samahani, wewe unaweza kunisaidia? (Excuse me, can you help me?)
It's important to note that "wewe" is a formal way of addressing someone. In casual conversation, you might use "nywe" (you), which is considered more informal.
