FAQs

How do I use "whether" in a sentence to express doubt?

You can use "whether" to introduce a clause expressing doubt between alternatives. For example, "I am unsure "whether to go" or stay home."

What's the difference between "whether" and "if"?

"Whether" is generally used to express a choice between two possibilities, while "if" introduces a condition. Although often interchangeable, "whether" is preferred when alternatives are explicitly stated. For example, "I don't know "whether or not" to go", versus "I'll go if it doesn't rain."

Can I use "that" after "whether"?

No, using "that" after "whether" is generally incorrect. "Whether" already introduces a subordinate clause, so adding "that" is redundant and grammatically incorrect.

What can I say instead of "whether or not"?

You can often simplify "whether or not" to just "whether" without changing the meaning. For example, "I'm not sure "whether to do it"" is equivalent to "I'm not sure whether or not to do it".
