Speaking clearly matters more than people realize. A single mispronounced word can distract from what someone is saying and even cause others to focus more on the mistake than on the message. English is especially difficult in this regard because its spelling system does not always match how words are spoken. Many words come from Latin, French, or other languages, and over time the pronunciation has shifted while the spelling stayed the same. This creates confusion and leads to common mistakes that almost everyone has heard before.
Some of these mispronunciations are so widespread that people assume they are correct, while others instantly irritate listeners who know the proper form. The most interesting part is that the reasons behind these mistakes are not random. Some errors come from childhood speech habits, others from spelling influence, and many from regional traditions. This list explores fifteen words people say wrong on a daily basis, explaining the correct way to pronounce them and why the mistakes happen so often. By learning these details, anyone can sound more confident and avoid the frustration that comes with language slip-ups.

Espresso
A cup of espresso is loved worldwide, but many people mistakenly call it “expresso.” The correct form is “espresso,” with no “x.” This error likely comes from people connecting it to the word “express,” since espresso is prepared quickly. The word actually comes from Italian, meaning “pressed out,” which refers to the method of forcing hot water through finely ground coffee under pressure. Mispronouncing it might not stop you from getting your drink at a café, but it often annoys baristas and coffee enthusiasts who know the difference.
Library
One of the most mispronounced words is “library.” Many people leave out the first “r,” saying “liberry” instead. The correct pronunciation is “library,” with both “r” sounds clearly included. Linguists explain this error as a result of “cluster reduction,” where children simplify difficult groups of sounds while learning to speak. The problem is that the habit sticks into adulthood for some people. Correcting this word requires slowing down slightly when speaking, which ensures that both consonants are present.
Nuclear
The word “nuclear” sparks debate almost every time it is brought up. The correct way to pronounce it is “new-clee-er,” yet a common mispronunciation is “new-cue-lar.” This mistake happens because people tend to rearrange sounds into more familiar patterns, in this case resembling words like “particular” or “molecular.” Interestingly, even politicians and public speakers have made this mistake on live television, which spreads the error further. Despite its prevalence, experts consistently note that “new-clee-er” remains the only accepted form.
Mischievous
The word “mischievous” looks straightforward, but many people mistakenly pronounce it as “mis-chee-vee-us.” This adds an extra syllable that does not exist. The correct version is “mis-chuh-vus,” with only three syllables. The error likely happens because people confuse it with similar words like “previous” or assume the spelling allows for an extra sound. Dictionaries and pronunciation guides are clear that the shorter form is correct. Paying attention to the rhythm of the word makes it easier to avoid the mistake.
February
Every year people struggle with “February.” Many drop the first “r” and say “Feb-yoo-ary,” but the correct form is “Feb-roo-ary,” keeping both “r” sounds. The reason for the dropped “r” comes from speech simplification, since pronouncing two “r” sounds close together is difficult. Despite this, the original Latin root “februarius” included the “r,” and formal English maintains it. Saying the full version correctly often feels awkward at first, but once learned it becomes a marker of careful and accurate speech.
Salmon
Few food words cause as much debate as “salmon.” The correct pronunciation is “sam-un,” with a silent “l.” Many people pronounce it as “sal-mon,” voicing the “l.” This mistake occurs because English speakers often assume every letter must be sounded, even though English has many silent letters from French and other languages. The “l” in salmon was included in spelling during Middle English reforms but was never meant to be spoken. Saying “sam-un” follows the original intention and remains standard today.
Often
The pronunciation of “often” has changed over time. The historically correct form is “off-en,” with a silent “t.” However, many people now say “off-ten,” voicing the “t” because it appears in the spelling. Linguists note that both forms are now acceptable in standard English, though “off-en” is still considered traditional and slightly more formal. The debate continues because dictionary authorities list both versions. Being aware of context helps, since “off-en” is preferred in formal speech, while “off-ten” is more common in casual settings.
Realtor
The word “realtor” is often stretched incorrectly into “real-a-tor.” The actual pronunciation is “real-tor,” with only two syllables. The mistake comes from the way the word looks, since people expect it to match words like “creator” or “mediator.” Professionals in the real estate industry strongly emphasize the correct version, partly because the word is trademarked and considered a professional title. Mispronouncing it not only sounds sloppy but can also be seen as disrespectful by those working in the field.

Comfortable
“Comfortable” confuses many because of the way it is spelled. Some pronounce all four syllables as “com-for-ta-ble,” but the correct and natural pronunciation is “comf-ter-bul.” This is a case of English simplification, where sounds are dropped to make speech flow more smoothly. Saying all the syllables makes the word sound forced, while the shorter version is accepted as standard. This type of contraction is common in English, and once recognized, it makes speaking more natural.
Coupon
The pronunciation of “coupon” varies by region. Some people say “koo-pon,” while others say “cue-pon.” Linguists recognize both as correct, though “koo-pon” is closer to the French origin from “couper,” meaning “to cut.” Supermarkets, television ads, and cultural habits influence which version people use. Because both are widely accepted, neither is wrong, but knowing the original form helps speakers understand why “koo-pon” is often taught as the standard.
Jewelry
The word “jewelry” is tricky because of its spelling. Many pronounce it as “jew-luh-ree,” adding an unnecessary syllable. The correct pronunciation is “jool-ree,” with only two syllables. This error happens because speakers instinctively try to pronounce every letter, even when the structure of the word condenses it. The confusion increases since older forms like “jeweller” and “jewellery” exist in British English, making the American spelling harder to process. Despite this, “jool-ree” remains the correct and efficient way to say it.
Almond
“Almond” is another word where the letter “l” causes problems. In most of American English, the “l” is silent, making the correct pronunciation “ah-mund.” However, many people pronounce it as “al-mond.” Both are recognized, but dictionaries tend to list the silent “l” first. This variation often depends on regional accent and family tradition. In California, where almonds are a major crop, locals almost always use the silent “l,” showing how local culture can affect language use.
Pronunciation
Perhaps the most ironic mistake is in the word “pronunciation.” Many people incorrectly say “pro-nounce-ee-ation,” inserting the “ounce” sound from the verb “pronounce.” The correct form is “pro-nun-see-ation,” without the extra syllable. This mistake is so widespread that it often goes unnoticed in casual speech. However, linguists emphasize that the noun form deliberately drops the “ounce” to maintain a consistent vowel pattern. Saying it correctly demonstrates careful attention to language and avoids a very common trap.
Data
“Data” is one of those words with multiple correct pronunciations. Some say “day-ta,” while others say “da-ta.” Both are acceptable in modern English, though preferences vary. In the United States, “day-ta” is often favored in professional and academic circles, while “da-ta” is common in everyday conversation. The variation shows how pronunciation can evolve based on usage. Knowing that both are valid allows speakers to adjust based on context and audience, which helps avoid criticism.
Peculiar
The last word on the list is “peculiar.” The correct pronunciation is “peh-cyoo-lee-er,” with all syllables present. A common mistake is “peck-yoo-ler,” which drops part of the middle. The shortened form is easier to say quickly, which is why people adopt it without realizing it is incorrect. Dictionaries consistently support the full pronunciation. Using the correct form adds clarity and prevents the word from sounding overly casual or careless.
These fifteen examples highlight how spelling, history, and habit shape pronunciation. Some errors come from regional influence, others from trying to simplify complex sounds. While many of these mistakes are common enough to be overlooked, mastering the correct versions shows attention to detail and respect for language. It also prevents misunderstandings and helps conversations flow more smoothly. Correct pronunciation might seem like a small detail, but it can make a strong impression in both casual and professional settings.
