- Whether means if or expressing a choice between two possibilities.
Examples

If you’re talking about rain, snow, wind, or temperature, use weather.
If you’re talking about a decision or possibility, use whether.
The Origin of Weather or Whether
Although these words sound alike today, they come from different Old English words.
Origin of Weather
The word weather comes from the Old English word “weder,” meaning air, wind, storm, or atmospheric conditions. It has been used for over 1,000 years to describe the state of the sky and climate.
Over time, the spelling became weather, but its meaning stayed almost the same.
Origin of Whether
The word whether comes from the Old English word “hwæther,” meaning “which of two” or “which one.”
Its purpose has always been to introduce choices or uncertainty.
Examples include:
- Whether we go today or tomorrow.
- I wonder whether it’s true.
Even though the pronunciation of these words became similar, their meanings never changed.
