the question whether (whether) etc.

Repeating whether in the same clause (e.g., "the question whether whether...") is a common drafting slip. The cure is simple: keep one whether, switch to "the question of whether," or recast as a direct question. Below are concise rules, quick checks, many before/after pairs for work, school, and casual writing, and practical memory tricks.

Quick answer

Never use "whether" twice to introduce the same subordinate clause. Keep a single whether, use "the question of whether," or rewrite as a direct question.

Wrong: The question whether whether we should accept the offer remains open.
Right: The question whether we should accept the offer remains open.
If it feels clumsy, recast: "Should we accept the offer?"

Core rule: one whether per clause

Whether introduces a subordinate clause that reports alternatives or doubt. Use a single whether for that clause. If you see two wh-words in a row ("whether whether"), remove the redundant one or rephrase the sentence.

Keep one whether: "The question whether we should go is settled."
Substitute: "the question of whether" + one whether, or convert to a direct question.

Wrong / Right: Wrong: The question whether (whether) we should go camping this weekend is still undecided.
Right: The question whether we should go camping this weekend is still undecided.
Wrong / Right: Wrong: The question whether whether the merger will pass is still up in the air.
Right: The question of whether the merger will pass is still up in the air.

Real usage and tone: formal, neutral, casual

Formal writing often prefers "the question of whether" to form a noun phrase. Neutral or concise prose can start directly with whether. Casual speech typically drops the leading noun phrase.

Formal: "The question of whether the policy complies with regulations remains."
Neutral: "Whether the policy complies with regulations remains to be seen."
Casual: "Whether we'll go depends on the weather."

Work:
Formal: The question of whether the committee will approve the plan remains unresolved.
School: Neutral: Whether this method works for the sample is still unclear.
Casual: Whether we're going is still up in the air.

Why writers repeat whether (and how to spot it)

Duplication often appears after copying and merging notes, adding parenthetical comments, or starting a sentence with a noun phrase like "the question whether" and then appending a clause that also begins with whether. The repetition is usually accidental.

Common triggers: merged edits, emphasis added without deleting, or hidden parentheticals.
Spot it fast: look for a noun phrase ("the question/issue") followed immediately by a clause that begins with whether.

Work - Wrong / Right: Wrong: Managers raised the question whether whether the new policy would affect Q3 projections.
Right: Managers raised the question of whether the new policy would affect Q3 projections.
School - Wrong / Right: Wrong: She wasn't sure of the question whether whether the data set included outliers.
Right: She wasn't sure whether the data set included outliers.

Fix your sentence: checklist and sample rewrites

Checklist: 1) Locate the subordinate clause introduced by whether. 2) Remove the redundant whether or the leading noun phrase. 3) If it still sounds awkward, rewrite as a direct question or split the sentence.

Three quick patterns: delete the first whether; replace "the question whether" with "the question of whether"; convert to a direct question.

Delete: "The question whether whether X" → "The question whether X."
Substitute noun phrase: "the question of whether X"
Direct question: "Will X happen?" or "Should we X?"

Rewrite:
Original: The question whether whether the client will sign is the main topic. Fix 1 (delete): The question whether the client will sign is the main topic. Fix 2 (substitute): The question of whether the client will sign is the main topic. Fix 3 (direct): Will the client sign? That's the main topic.
Rewrite:
Original: We need to address the question whether whether the sample size is sufficient. Fix: We need to address whether the sample size is sufficient.
Work - Rewrite:
Original: The committee discussed the question whether whether to postpone the vote. Fix: The committee discussed whether to postpone the vote.

Examples library: work, school, and casual pairs

Short wrong/right examples you can copy or adapt. Each wrong sentence shows a common duplication source; the right sentence shows the simplest correction. Alternates appear where useful.

Try your own sentence

Test the whole sentence in context. If you see two wh-words adjacent, remove the first and read aloud; if meaning and flow are preserved, keep the change.

Memory tricks and quick heuristics

Use brief checks while proofreading to catch duplicates without deep grammar study.

Mnemonic: One whether per clause.
Heuristic: If you spot "the question whether whether X," delete the first whether and read the sentence.
Edit tip: Turn the sentence into a direct question-clarity often follows.

Spacing, punctuation and small style points

Punctuation can hide duplicate whether, but it doesn't make duplication acceptable. Fix the grammar first, then adjust commas and parentheticals.

Don't rely on commas or parentheses to justify duplication: "The question, whether (whether) we should proceed" is still wrong.
After correcting duplicate whether, check for comma placement around clauses as usual.

Wrong / Right: Wrong: The question, whether (whether) we should proceed, is still open.
Right: The question of whether we should proceed is still open. Alternate: Whether we should proceed is still open.

Hyphenation and grammar points (what not to do)

Hyphens won't fix this: do not write "whether-whether" or attempt to mask duplication with punctuation. Treat it as a rewrite task.

Also note the if vs whether distinction: after nouns like "the question" or "the issue," whether is the clear choice in formal contexts.

"Whether or not" is two words; do not hyphenate.
After "the question" use "whether" (not "if") in formal writing: "the question of whether the plan will work."

Wrong / Right: Wrong: We debated whether-whether to accept the contract.
Right: We debated whether to accept the contract.
School - Wrong / Right: Wrong: The question whether if the sample is biased remains.
Right: The question of whether the sample is biased remains.

Similar mistakes to watch for

Related errors include using if where whether is required, stacking multiple whether-type constructions, and keeping redundant qualifiers after "the question."

If vs whether: prefer whether for alternatives or formal reporting clauses; if can change nuance.
Avoid stacking: "whether or not whether" usually needs a rewrite.
Trim qualifiers: don't follow "the question of whether" with extra words that merely repeat the idea.

Work - Wrong / Right: Wrong: We're unsure whether if the client will sign.
Right: We're unsure whether the client will sign.
Casual - Wrong / Right: Wrong: She asked whether whether or not the band would play tonight.
Right: She asked whether the band would play tonight.

FAQ

Is it correct to say "the question whether whether"?

No. That repeats whether. Use a single whether or replace the phrase with "the question of whether" followed by one subordinate clause.

When should I use "the question of whether" instead of just "whether"?

"The question of whether" suits formal prose when you want a noun phrase subject. For tighter writing, start with whether. Either way, use only one whether.

Should I use if or whether after "the question"?

Use whether. After "the question" the clearer, more formal choice is whether; if can be informal or ambiguous.

How can I detect a duplicate whether quickly?

Scan for a noun phrase like "the question whether" and a clause that immediately begins with whether. Reading the sentence aloud makes duplication obvious.

Will grammar checkers catch repeated "whether"?

Many checkers flag repeated words and suggest fixes, but review suggestions: tools can propose stylistic changes that may not match your intended tone.

Try a quick rewrite

If you suspect duplication, paste a sentence into your editor and try three quick rewrites: delete the first whether, replace with "the question of whether," or turn the sentence into a direct question. Practicing these patterns makes the single-whether rule habitual.
