The case
The name is obviously built from "fabric" and "breeze," so the spelling should be Febreeze. The bottle disagrees and has since the product went national in 1998: F-E-B-R-E-Z-E.
This one is a favorite because the misspelling is so reasonable. The brand pun invites you to spell "breeze" correctly, and the trademark deliberately doesn't.
Why our brains do this
A coined name that sounds like a real word gets spelled like the real word.
