Understanding Whatnot vs What Not: Correct Usage and Meaning
Writers, editors, and students regularly stumble over “whatnot” versus “what not.” The two look alike yet behave differently, and misusing them can dent credibility in academic papers, business emails, and marketing copy alike.
This guide dissects their histories, meanings, grammatical roles, and stylistic nuances. You’ll walk away with practical tricks, real-world examples, and quick-reference rules that eliminate guesswork forever.
Etymology and Historical Development
Origin of “whatnot” as a single word
In the 1500s, English speakers began using “whatnot” to cap off a list of unspecified items, literally signaling “and anything else you might think of.” The compound quickly solidified into one word, dropping the space and hyphen as printers standardized spelling.
Antique furniture called a “whatnot shelf” appeared in the 18th century, further cementing the single-word form in both speech and trade.
Evolution of “what not” as two separate words
“What not” as an interrogative phrase traces back to Old English “hwæt nāht,” where “nāht” meant “nothing.” Over centuries the phrase split into everyday questions such as “what not to do.” Unlike its cousin, it never merged into one word because its grammatical role stayed flexible.
Core Meanings in Contemporary English
“Whatnot” as an indefinite placeholder
Modern usage treats “whatnot” as a catch-all noun meaning miscellaneous objects or trivial details. Example: “Grab the chargers, cables, and whatnot from the drawer.”
The word signals that further enumeration is tedious or unnecessary.
“What not” as an interrogative or negation phrase
When separated, “what not” typically introduces a negative question or lists forbidden actions. Example: “Tell me what not to pack for a glacier hike.”
The space between the words keeps the interrogative force alive.
Grammatical Roles and Part of Speech
Noun function of “whatnot”
As a noun, “whatnot” replaces the cumbersome phrase “miscellaneous items.” It can be pluralized—“whatnots”—though this is rare outside antique-dealer jargon.
Phrase function of “what not”
“What not” acts as an open interrogative phrase or as part of an infinitive clause. Example: “She explained what not to touch in the lab.”
The phrase never stands alone as a noun, which prevents confusion once you grasp the pattern.
Spelling Conventions and Style Guide Preferences
Major dictionaries and their stance
Merriam-Webster lists “whatnot” as a single noun and labels “what not” as an idiomatic phrase under “what.” Oxford mirrors this split, noting the hyphenated variant is archaic.
AP and Chicago style guides both recommend the closed compound for the noun sense and two words for the interrogative sense.
Corpus frequency data
Google Books N-gram data shows “whatnot” rising steadily after 1950, while “what not” as a phrase remains flat. This divergence underlines modern preference for the compound when indicating miscellaneous items.
Real-World Usage Examples in Context
Business and technical writing
Business emails benefit from concise placeholders: “Order laptops, adapters, and whatnot by Friday.”
Technical manuals, however, favor precision and seldom use “whatnot” unless addressing non-critical accessories.
Creative and literary writing
Novelists relish the colloquial flavor of “whatnot.” In Donna Tartt’s “The Goldfinch,” characters toss the word into dialogue to sound natural without cluttering the page with exhaustive lists.
Academic and research contexts
Academic prose avoids “whatnot” because it signals vagueness. Instead, scholars write “miscellaneous variables” or “additional parameters.”
Yet footnotes may quote speech that includes “whatnot,” preserving authenticity.
Common Mistakes and How to Avoid Them
Confusing the noun with the phrase
Mistake: “Please review the contract and highlight what not need amendments.” Corrected: “Please review the contract and highlight what does not need amendments.”
The error stems from forcing the phrase into a noun slot.
Overusing “whatnot” in formal prose
Formal reports that sprinkle “whatnot” read as careless. Replace with “and other related items” or a precise list.
Hyphenation errors
Writers sometimes insert a hyphen—“what-not”—but dictionaries deprecate this form except in historical contexts.
Practical Tips for Editors and Content Creators
Quick substitution test
If “miscellaneous items” fits grammatically, use “whatnot.” If the sentence still needs “what” plus a negation, keep the two-word form.
Voice and tone calibration
Blogs targeting hobbyists can freely use “whatnot.” White papers should swap it out for specificity.
Global audience considerations
Non-native speakers often parse “whatnot” as “what not,” causing confusion. Provide context or rephrase for clarity.

Short, punchy sentences pair well with “whatnot.” Example: “Keys, wallet, whatnot—he dumped everything on the counter.”
Elliptical constructions
Writers sometimes drop the verb after “whatnot.” Example: “Papers, pens, whatnot strewn across the desk.” The ellipsis adds urgency.
