Welsh speakers have expressed their anger at the decision to grant a company exclusive use for the word "cariad", meaning love.
Cariad was granted as a trademark to scented candles company Fizzy Foam Candles.
The word was submitted to Newport-based UK Intellectual Property Office for the exclusive right to name their candles after the concept. Other uses for the Cariad would not be the copyright of Fizzy Foam.
In the streets of Cardiff many said they were "digofaint" (or livid) about the decision.
