Why

Merriam-Webster: weather is the noun for atmospheric conditions (and a verb meaning to withstand); whether is a conjunction. They are homophones in most accents, so the mistake is a spelling slip rather than a grammar one.

Examples

  • The weather turned cold overnight.
  • I don't know whether to stay or go.
