1. Silohouette
   Silhouette
2. Silohuette
   Silohoette

"Silhouette" has got to be one of the hardest English words to spell! Referring to the shape or outline of something, this word comes to English from the French, inspired (for mysterious reasons) by an 18th century French politician and writer, Étienne de Silhouette.

1. Embarassing
   Embarrasing
2. Embarrassing
   Embarasing

We all hate being embarrassed, but we might hate trying to spell "embarrassing" even more! Just try to remember the double r and double s.

1. Pharaoh
   Pharoh
2. Phairoh
   Pharroah

This word migrated to English in an interesting way. Starting off as the Egyptian word pr-‘o, which means "great house", it then became the Hebrew par‘ō, Greek Pharaō and Latin Pharaoh before joining Middle English vocabulary. Today it refers to ancient Egyptian kings.

1. Chaffeur
   Chaufeur
2. Chauffeur
   Chauffer

Another word borrowed from the French! Meaning "personal driver", a chauffeur isn't just a person driving a limousine. Technically, you could call your cabbie a chauffeur!

1. Tommorrow
   Tomorow
2. Tommorow
   Tomorrow

"Tomorrow" is a Middle English word combining two words, "to" and "morrow", which means "the next day". We don't say morrow very often, but tomorrow is still an essential part of our vocabulary.

1. Miniscule
   Minuscule
2. Minascule
   Minescule

Meaning "tiny," minuscule is a little word that can give spellers a huge amount of trouble! We remember it by using the "two u's" rule.

1. Hierarchy
   Hiararchy
2. Hiorarchy
   Hierorchy

A "hierarchy" is a system where different members have different ranks. Examples include the Catholic Church, major league baseball and your local high school! Originally a Greek word, we can't spell this one without a dictionary!

1. Acomodate
   Acommodate
2. Accommodate
   Accomodate

Meaning "to provide space for or to adapt to", this word is not very accommodating to our spelling needs! As this word came to English straight from Latin, we guess that's to be expected.

1. Calender
   Calendar
2. Calander
   Callendar

"Calendar" comes from the Latin word "kalendarium", which means "account book". We always want to spell the end of it as "-der", because that's how it's pronounced.

1. Rapore
   Raport
2. Rappore
   Rapport

It sounds like a very serious report, but "rapport" means the closeness that can arise between two people or a group. It comes from an old French word that means "bring back". It's hard to spell because of that final "t"!

1. Prerogative
   Perogative
2. Preragative
   Peragative

Meaning "a right or privilege that a specific person or group has", prerogative is — you guessed it — another word that comes to us from Latin. It's not said very often, but the 1989 Bobby Brown song "My Prerogative" made it briefly famous.

1. Antediluvian
   Antidiluvian
2. Antedeluvian
   Antidiluvien

Meaning "the time before the Biblical flood that spurred Noah to build his ark", antediluvian's spelling is easier to remember if you remember that "ante" means "before" in Latin. Use antediluvian to mock anything you think is old-fashioned; that's the word's most common usage today.

1. Brussels sprouts
   Brussel sprouts
2. Brussal sprouts
   Brussals sprouts

The Brussels sprout is actually a Mediterranean vegetable, but English speakers first encountered them in the city of Brussels, Belgium — hence the name. Most people are tempted to spell this word "Brussel sprouts", as that extra s can be hard to remember. That's why this otherwise easy word made it into this quiz!

1. Saphire
   Sapphire
2. Saffire
   Sapphirre

One of the world's most beautiful jewels, the sapphire's name is actually a misnomer. It comes from the Greek word "sappheiros", which refers to lapis lazuli, another stunning blue stone.

1. Oger
   Oagr
2. Ogre
   Ogr

Many people have fond memories of Shrek, but originally, the word "ogre" referred to man-eating giants from French folklore. But they were named after the Etruscan god Orcus, who was a cannibal. We know little of ancient Etruscan culture, so it's fascinating that a bit of their mythology still lives on in our society.

1. Terodactyl
   Pterodactyl
2. Ptearodactil
   Ptearodactyl

"Pterodactyl" might be hard to spell, but these dinosaurs were undeniably cool. They were a small, flying dinosaur that flourished during the Jurassic Period.

1. Pennitentiary
   Penitintiary

   Penitentiary

This is a uniquely American term for prison. It comes from a Latin word, penitentiaria, which means “place of penitence”, and was first used by Quakers in the 18th century.

1. Maintainance
   Maintanence
2. Maintenance
   Maintanance

This word is French, French, French! Spelling it is difficult because it's hard to know where to use an a and where to use an e. We don't have any tips for remembering how to spell it, other than not being afraid to rely on your spellcheck!

1. Pronounciation
   Prononciation
2. Pronenciation
   Pronunciation

"Pronunciation" is difficult to spell because "pronounce" is spelled so differently. The human tendency toward logic and consistency makes us expect "pronunciation" to be spelled "pronounciation", but that's just not the case. This word has been tripping up spelling bee competitors for years!

1. Wildebeest
   Wildebeast
2. Willdebeast
   Willdebeest

This is a Dutch/Afrikaans word that literally means "wild beast". However, the animal it refers to, the gnu, is a large antelope that is similar to wild cattle in character — hardly a dangerous slavering beast.

1. Realize
   Realise
2. Reallize
   Reallise

British people spell this word with an s, while Americans spell it with a z. With two spellings that are technically correct, "realize" can really be confusing to spell!

1. Kilemoter
   Kilometer
2. Kilometor
   Kelometer

In the U.S., this word is spelled "kilometer", while outside the U.S., it's spelled "kilometer". That's what makes this word truly tricky! It refers to a distance of 1,000 meters, or .62 miles.

1. Hackneed
   Hackaneed
2. Hackneyed
   Hacknead

Nowadays we often say "hack" instead of "hackneyed", but the meaning is the same: lazy and inept. In England, before there were automobiles, a "hackney" was a sort of horse-drawn cab. When the word "hackneyed" was coined, calling something "hackneyed" meant you were calling it cheap, as most wealthy people during that period of time had their own carriages.

1. Camaflage
   Camuflage
2. Camoflage
   Camouflage

The nickname for camouflage clothes is "camo", but it might as well be "camou"! Camouflage was invented by the French during World War I, which is why we're stuck with this difficult spelling.

1. Machete
   Mashete
2. Machette
   Mashetty

The machete is a large knife, originally invented in the Caribbean and South America. It comes from the Spanish word "macho", which means hammer.

1. Carribbean
   Carribean
2. Caribbean
   Caribean

The region and culture known as "the Caribbean" are named after the Carib or Caribe, a people who lived in the West Indies. Many North American islands are located in the Caribbean, including Jamaica, the Bahamas, Haiti, Cuba, Saint Martin, Grenada and Aruba.

1. Dachound
   Dachshound
2. Dachshund
   Dachshund

"Dachshund" is a German word meaning "badger dog". The breed was originally developed for digging up badger holes (apparently something that was a big problem in the 19th century). In the U.S., we pronounce this name as "doxen" and are as likely as not to call these dogs "hot dog dogs".

1. Liassion
   Liasion
2. Liason
   Liaison

Another French word with a wild, wild spelling, "liaison" is almost impossible to spell without a dictionary. This word refers to a person who is acting as a go-between for two people or groups.

1. Ancilliary
   Ansillary
2. Ancillary
   Ancillarye

"Ancillary" is an adjective that refers to something or someone that is functioning in a supporting role. Oddly, it comes from the older English word "ancilla", which means "maidservant".

1. Ectasy
   Ecstasy
2. Ectacy
   Ecstacy

Another of those terrifically difficult Greek words, "ecstasy" come from the Greek word ἔκστασις, or ékstasis. In English, we use it to refer to pleasure, especially sexual pleasure, but its original meaning had more to do with unusual states induced by religious feelings.

1. Sepulchre
   Sepulcher
2. Sepulchar
   Sapulchre

This grim word means "burial place or monument made of stone". In the United Kingdom, it's spelled "sepulchre", but Americans spell it "sepulcher".

1. Avacado
   Avocado
2. Avocodo
   Avecado

This delicious vegetable is actually a fruit. It's also spelled with fewer a's than you'd think!

1. Anacronistic
   Anachronystic
2. Anachronistic
   Annachronistic

This word means "in the wrong time". You might use it to refer to a "lords and ladies" movie where people say "cool", or you might use it to gently mock something old-fashioned, such as an 8 p.m. curfew for an eighteen-year-old. Either way, this word is much easier to say than to spell!

1. Millennial
   Milennial
2. Milenial
   Millenial

People love to claim that millennials are ruining everything, but the real problem is the person who decided to call millennials "millennials", because it's caused everybody a lot of spelling issues. This word has two n's, three l's and too much media coverage!

1. Senater
   Senoter
2. Senator
   Senotor

We've included this word in the quiz because it's always so tempting to spell "senator" as "senater". The correct -or ending makes a senator sound like some sort of advanced robot, i.e. the Senator 5000.

1. Sekoia
   Secoia
2. Sequoya
   Sequoia

Sequoias are tall trees. They're named after a revered Cherokee Native American historical figure who was called Sequoyah. He invented the first Cherokee writing system.

1. Occasion
   Ocasion
2. Ocassion
   Occassion

It's a momentous occasion when we spell "occasion" right, as this word sounds like it should be spelled "ohkayshun"! It comes to us from the Late Middle English and is a very useful word, which is inconvenient for most spellers.

1. Filmmaking
   Filmaking
2. Fillmaking
   Film-making

Some style guides have you hyphenate filmmaking; others do not. Either way, it's a word you usually have to look up to get right, which is why it's part of this quiz!

1. Daiquiri
   Daquiri
2. Daqueri
   Daiquari

A daiquiri is a fantastic cocktail, generally containing rum and juice. It's named after the Cuban region from which it comes. We recommend drinking it rather than spelling it!

1. Queue
   Queu
2. Que
   Qeue

Meaning "a long line or extended braid", queue is remarkable for containing way more vowels in a row than most English words. That's because it comes from a French word, of course! Originally, it meant "horse's tail".
