Can You Spot the Fake Word?
Three real words, one impostor, seven rounds — how sharp is that vocabulary of yours, really?
English is a hoarder. It has kept words for canal-watchers, stomach growls, and people who lecture outside their expertise, then buried them where almost nobody looks. That attic of forgotten vocabulary is exactly where this game lives.
Each round shows you four words. Three are genuine English, dusty but documented. One came straight out of my imagination this morning. Your job is to point at the impostor without flinching. Fair warning from your big sis: the real ones sound faker than the fakes. Trust nothing, especially the cute ones.

Inspect the scoring, question by question
The highest possible score here is 21. The original game divides scores into 4 bands; the bands contain different numbers of answer combinations. A high point total is not a measured percentile.
1. Round one. Which of these four words did we invent?
- Widdershins — 1 original points
- Plorvish — 3 original points
- Snickersnee — 2 original points
- Petrichor — 0 original points
These are the archived game’s option weights. Partial credit is a game rule, not a clinical or population measurement.
2. One of these has never appeared in any dictionary. Find it.
- Mumpsimus — 2 original points
- Borborygmus — 1 original points
- Cromblet — 3 original points
- Gongoozler — 0 original points
These are the archived game’s option weights. Partial credit is a game rule, not a clinical or population measurement.
3. Three of these are legitimate English. Point at the fraud.
- Taradiddle — 1 original points
- Absquatulate — 2 original points
- Hornswoggle — 0 original points
- Snerrivance — 3 original points
These are the archived game’s option weights. Partial credit is a game rule, not a clinical or population measurement.
4. The impostor is hiding among some very real insults. Which is it?
- Vintrical — 3 original points
- Blatherskite — 1 original points
- Flibbertigibbet — 0 original points
- Snollygoster — 2 original points
These are the archived game’s option weights. Partial credit is a game rule, not a clinical or population measurement.
5. Everyday objects this time — except one word names nothing at all.
- Ferrule — 1 original points
- Gnomon — 2 original points
- Murlop — 3 original points
- Aglet — 0 original points
These are the archived game’s option weights. Partial credit is a game rule, not a clinical or population measurement.
6. Fancy company in this round. Which word is the counterfeit?
- Sesquipedalian — 0 original points
- Glissorne — 3 original points
- Bibliopole — 2 original points
- Ultracrepidarian — 1 original points

Recognising a word is far easier than producing one
Your recognition vocabulary is enormous compared with the words you actually deploy. Checklist studies, in which people tick the words they know, put educated adult English speakers somewhere between twenty and thirty-five thousand word families, though the figure moves depending on how a family is counted.
Those studies have an obvious flaw, and researchers solved it in the same way this quiz does. Sprinkle invented words through the list. Anyone ticking those is over-claiming, and the score gets adjusted downward. A game of spot the impostor is a vocabulary instrument with the lid off.
Why a made-up word can feel completely legitimate
English permits certain sound sequences and forbids others, a system linguists call phonotactics. Plorvish obeys every rule: a licensed opening cluster, vowels where English likes them, and an ending you have seen on real adjectives. That is why it slides past unchallenged while an impossible run of consonants would not.
Jean Berko showed in 1958 how deep this runs. She presented children with a drawing of an invented creature called a wug, then a second one, and the children happily said there were two wugs. They had never heard the word, yet applied the plural rule without hesitation. Your sense that something sounds like a word is a genuine competence at work. It simply cannot tell you whether a dictionary agrees.
Word memory is not a filing cabinet
Endel Tulving drew a distinction that helps here: semantic memory holds facts stripped of their origins, while episodic memory holds events you can place in time. You know what an aglet is without recalling where you learned it, which is semantic memory working as designed.
It is also fallible in a slightly unsettling way. In the paradigm Henry Roediger and Kathleen McDermott revived in 1995, people study a list of related words such as bed, rest, tired and pillow, then confidently report having seen the word sleep, which was never presented. Confident recognition and accurate recognition are different things, worth remembering when a word here feels unmistakably familiar. To be plain: a word game cannot tell you anything about the health of your memory. If your memory has genuinely worried you, that is a conversation for a doctor, not a quiz page.
What the score is worth
Mostly it reflects reading history. People who read older fiction or dialect writing meet words like slugabed and blatherskite naturally. That is exposure, not verbal ability in any technical sense, and certainly not intelligence.
