Conclusion

Whether or not is a simple but powerful phrase. It shows two possibilities and often appears when people talk about decisions, doubts, or outcomes that happen anyway.

You can shorten it to whether when the meaning is clear, but the full form adds emphasis and works well in formal writing.

If you remember one rule, make it this: use whether for choices—and add or not only when you want to stress both sides.

Clear writing starts with small grammar wins like this one.
