Homophones are words that sound the same but have different spellings and meanings.
However, you could use the word "seller" in some contexts, as they sound very similar. "Seller" refers to someone who sells something.
For example:
* "The old cellar was full of cobwebs."
* "The seller of the house was very eager to close the deal."
Keep in mind that "seller" is not a perfect homophone, as the pronunciation slightly differs depending on the accent.
