This is the 2109th most frequent Chinese word.
嘛
"嘛" is a particle used to emphasize, suggest, or explain, often implying "obviously" or "as you know."
The '嘛' particle at the end of the sentence adds emphasis and urges the listener to comply or provide the information requested.
你告诉我嘛！
You just tell me!
The '嘛' particle serves to assert and confirm the simplicity of the matter with a casual and confirming tone.
这个事情很简单嘛。
This matter is quite simple.
Here, '嘛' is used to imply an obviousness or given reasoning, expressing that the fact stated should be self-evident or understood.
