Whether or Not – Quick Answer

The correct phrase is “whether or not”.

• ✅ Example: I don’t know whether or not she will come.
  
• ❌ Wrong: I don’t know wether or not she will come.
  

“Wether” is a real word, but it means a castrated male sheep—nothing to do with choices or conditions.

The Origin of Whether or Not

• Whether comes from Old English hwæðer, meaning “which of the two.”
  
• Wether comes from Old English weðer, meaning a male sheep.
  
• Weather comes from Old English weder, meaning air or sky.
  

All three sound similar, which is why people still confuse them today. The phrase “whether or not” has been in use since at least the 14th century.

FAQs:

1. Is “whether or not” ever correct?

2. What does “whether or not” mean?

3. Can I just use “whether”?
Yes, often. Example: I don’t know whether she’ll come. Both forms are correct.

4. Why do people type “weather”?
Because it sounds identical to “whether” in speech.

Think: weather = sheep, weather = rain, whether = choice.

Conclusion

The phrase “whether or not” is the only correct spelling when expressing choices, possibilities, or conditions.

The confusion comes from the homophones weather (a sheep) and weather (climate), but those meanings don’t apply here.

Across both British and American English, the rule is the same: always write “whether or not.” It’s clear, professional, and universally accepted. Remember—using the wrong spelling in emails, essays, or reports can look unprofessional.

When in doubt, keep it simple: whether = choice.
So next time, you’ll know exactly whether or not you’re spelling it right.
