I discovered a new word today – rememberer – it means one who remembers, and in sociolinguitics it has a more specific meaning:

“One who remembers several words and phrases from a moribund language, but never became fluent in it.”

I came across this word on Wikipedia in an article about the Southern Pomo language, which states that “In 2012 there was one fluent speaker, from Dry Creek, one rememberer, and a handful of people who learned some vocabulary as children.”

Does anyone know that the current situation is for Southern Pomo?

The article mentions revival efforts, but I can’t find anything more recent about the state of the language.

Related words include rememberancer – a person who reminds someone, and reremember – to remember again. So someone who remembers again would be a rerememberer.
