Have you ever typed marshmallow into Google and paused, unsure if it should be marshmallow or marshmellow? You’re not alone.
This is a very common spelling mistake, even for native English speakers.
The confusion happens because of how the word sounds. When spoken, the middle part is soft and unclear, making both spellings seem possible. As a result, many people guess the spelling instead of being sure.
People search for marshmallow or marshmellow because they see both forms online.
One appears in casual writing and social media. The other is used in dictionaries, recipes, packaging, and formal text. This leads to doubt: is one British, one American, or is one simply wrong?
This guide clears the confusion fast. You’ll learn the correct spelling, why the mistake happens, and how to use the word confidently in writing.

The Origin of Marshmallow or Marshmellow

The confusion becomes easier to understand when you know the history of the word marshmallow.
The word comes from two older words:
- Marsh → a wetland or swamp
- Mallow → a flowering plant (mallow plant)
Long ago, people extracted sap from the marsh mallow plant (Althaea officinalis). This sap was used to make early versions of the sweet we now call marshmallow.
Over time:
- Marsh mallow became marshmallow
- The spelling stabilized in English
- The pronunciation softened, making the middle sound unclear
Why “marshmellow” appeared
The spelling marshmellow appeared because:
- People pronounce the word quickly
- The “a” sound in mallow sounds like “eh” or “uh”
- Writers spell by sound instead of history
However, this spelling never became standard. Dictionaries, publishers, and language authorities all kept marshmallow as the correct form.
British English vs American English Spelling
Unlike many spelling debates (color vs colour, organize vs organise), this is not a British vs American difference.
Both British English and American English use the same spelling.
