It's important to note that the meaning can be slightly nuanced depending on the context. It could also mean "died" in the sense of something ceasing to exist or being destroyed.
For example:
* "Ente amma achichanu" (My mother died)
* "Aayiram nambukal achichanu" (A thousand hopes died)
It's always a sensitive topic to discuss death, so it's important to be mindful of the context and the feelings of others when using this word.
