weather/whether or wether
The words wether, weather, and whether sound identical, but their meanings are very different.
What is the difference between wether, weather, and whether?
Wether – A wether is a castrated ram (male sheep).
Weather – Weather refers to the state of the atmosphere (e.g., temperature, wind, clouds, rain).
Whether – Whether is a conjunction with a similar meaning to if (e.g., I wonder whether it will rain.)
Some people have suggested that a helpful way of remembering the difference is to associate weather with the sea, which also contains the combination ea: so by remembering the weather on the sea you will remember which is which.
