Mayonnaise vs. Mayonnaise – What’s the Difference?

Have you ever paused in the grocery aisle staring at the salad dressings and wondered: “Is it spelled mayonnaise or mayonaise?” You’re not alone. This little condiment has stirred more than sandwiches—it’s stirred confusion. Let’s clear things up, dive deep into the creamy spreads world, and learn everything you need to know. We’ll explore the correct spelling, its origins, why the misspelling happens, and how the correct term appears in dictionaries and everyday usage. By the end, you’ll spot the difference instantly and use the right word confidently in your writing, cooking, and conversation.

The Quick Answer: Only One Is Correct

Here it is straight: “mayonnaise” is the correct spelling. The term “mayonaise” is a common misspelling.
Why? Because of how the word sounds and how people guess at spelling. The missing “n” in “mayonaise” makes sense phonetically (you hear “may-uh-naze”), but spelling-wise, it’s incorrect. So whenever you write about that creamy spread, stick with mayonnaise.
In casual speech, some might write “mayo” for short. That’s fine — but make sure the full version is spelled right if you’re writing for blogs, menus, or labels.

Origin and Etymology of “Mayonnaise”

The word mayonnaise has a fascinating and somewhat murky history. Historians debate exactly where and when it began. Here are some of the main theories:

• One theory ties it to the capture of Port Mahón in Minorca (Spain) in 1756 during the Seven Years’ War. Supposedly, a chef celebrated the victory with a sauce made of egg and oil and named it mahonnaise after Mahón.Another theory says the word derived from the French verb manier (meaning “to handle” or “to stir”), because cooking mayonnaise involves vigorous mixing. Yet another suggests it comes from the Old French moyeu (meaning “egg-yolk”) → moyeunaise. That reflects the central role of egg yolk in the emulsion.
• Still others believe it comes from the French town of Bayonne (“bayonnaise”). 

What’s certain: by the early 1800s the word “mayonnaise” is in French cookbooks. The condiment as we know it—a thick emulsion of oil, egg yolks, and vinegar/lemon juice—traces its modern form to French haute cuisine. 

Why People Misspell It as “Mayonaise”

It happens so often you’d think the misspelling is correct — but here’s why it’s deceptive:

• Phonetics: The drop of the “n” reflects how many people pronounce it. “May-uh-naze” doesn’t emphasise the “n” before the “a,” so the spelling gets simplified in their minds.
• Simplified Spelling Trend: English writing often seeks shortcuts. Dropping a letter or two seems harmless if it “sounds right.”
• Lack of Awareness: If someone didn’t study the etymology or check a dictionary, they might assume the simpler version is fine.
• Typing/Auto-correct: Digital typing can introduce mistakes or accept alternative spellings.
• Other words for food spelled weirdly: For example, “tomatoes” often becomes “tomatos.” That normalizes sloppy spelling.

Here’s a quick list of other food words people commonly mis-spell:

• “mischievous” (often written as “mischevious”)
• “zucchini” (often “zuchini”)
• “quinoa” (often “keen-wa” spelled “kinwa”)
• “muscle” (often “mussel” when confused)

Remember: if it looks odd, double-check. For mayonnaise, always use –n-n-a-i-s-e.

How Dictionaries Define Each

Here’s a table summarizing dictionary recognition of the two terms:

Dictionaries like Merriam-Webster, Oxford English Dictionary, and Etymonline list mayonnaise and its French/Spanish origins. They do not list “mayonaise” as a valid variant

Is “Mayonaise” Ever Used Anywhere?

You might wonder: so if “mayonaise” is wrong, does it appear at all?

• Online and informal writing: Yes. Blogs, social media, user comments often show “mayonaise.” It reflects typing error or linguistic simplification.
• Branding or stylised names: Some small businesses might adopt quirky spellings intentionally (though rare for food condiments where trust matters).
• Non-native English contexts: In regions where English is taught but less emphasised, the misspelling might persist.
• Not in major dictionaries: As noted above, major lexicons do not approve “mayonaise.” So if you are writing professionally, academic-ally, or for branded content, use the correct one.

Bottom line: “mayonaise” might occur, but it’s not officially “valid.” If you want to appear authoritative, use mayonnaise.

Pronunciation: They Sound the Same

Here’s the simple truth: you pronounce both “mayonnaise” and the misspelled “mayonaise” the same way — but that doesn’t make them the same word.

Pronunciation Guide

• /ˈmeɪəneɪz/
• Sounds like: may-uh-naze
• In casual speech many say: “MAY-oh” (for short)

Since pronunciation doesn’t guide the spelling difference, you must rely on memory or reference to get the word right.
Think: “May-on-naise” — double “n” after “may-on”
