If you’re talking about choices or possibilities, always use whether.


The Origin of Wether or Whether

The word whether comes from Old English hwæðer, meaning “which of two.” It has been used for centuries in English writing to indicate choice or doubt.

Wether, on the other hand, comes from Old English wether, specifically referring to a castrated male sheep. The similarity in pronunciation has caused confusion over time, but their meanings have always been very different.


British English vs American English Spelling

Interestingly, “whether” is the same in both British and American English

Similarly, “wether” remains unchanged across English varieties, but it is rarely used except in farming or livestock contexts.
