The correct English spelling is “mayonnaise,” not “mayonaise.” Mayonnaise is the standard spelling for the thick, creamy sauce made primarily from oil, egg, and an acidic ingredient such as vinegar or lemon juice.
For example, you would write, “I added mayonnaise to my sandwich.”
Mayonaise is a common spelling mistake, especially because the word can be difficult to spell and pronounce.
The confusion is understandable because mayonnaise contains several vowels and its pronunciation does not clearly reveal every letter.
However, in standard English writing, mayonnaise is the form you should use.
Whether you are writing a recipe, restaurant menu, school assignment, food article, shopping list, or everyday message, choose mayonnaise.
Quick Answer
Mayonnaise is the correct English spelling. Mayonaise is a misspelling. Mayonnaise is a creamy sauce commonly made with oil, egg, and an acidic ingredient such as vinegar or lemon juice. Remember the spelling as M-A-Y-O-N-N-A-I-S-E: mayonnaise.
Why Do People Confuse “Mayonnaise” and “Mayonaise”?
People often confuse these spellings because mayonnaise is not pronounced exactly as it looks.
The word contains several letters that can be easy to overlook:
mayonnaise
A common mistake is dropping one of the n’s and writing:
mayonaise
The correct spelling contains two n’s:
mayonnaise
It also ends in -aise, not simply -aise after removing the extra n.
Another reason for the confusion is that the word has been borrowed into English from French. Its French spelling is also mayonnaise, so the standard English spelling retains this form.
