These two homophones are tricky buggers for many of us. Why? Because they sound the same, and they look awfully close in spelling. Here’s how to remember the difference between the two.
Weather; N. –the condition of the atmosphere or climate
The weather outside is frightful.
Weather; V.–the act of wearing down by erosion
The horse saddle began to weather and cracked in the hot sun.
Whether; Conjunction–used to introduce alternatives
He had to decide whether or not to eat another fajita.
The trick is simple–the “a” in weather should remind you of atmosphere (rain, snow, sun, etc.)
If you’re still not sure, a synonym for whether is if. He had to decide whether (if) or not to eat another fajita. Is it a bit awkward? Yes. Doe it help? Sure!
