Tony Scott Warren, the Jersey French language officer known as Offici du [l’]Jèrriais, said: “It is a worry. We’re making efforts to educate as many people as possible. It’s not surprising we are on the list. The numbers have been declining for a long time.” He estimates that about 1,000 native speakers remain. “We are looking to develop the range of what we’re doing to get more people involved,” he said.
