Can anyone translate this phrase for me please? It would be better if it were in Sindarin. I think this is a quote from Tolkien, too.

A story must be told or there will be no story, yet it is the untold stories that are most moving.

Also, I would really like to know what you do. Are you linguists? Teachers? Or just Tolkien maniacs like me (although I'm just 6th grade)?

Annon allen! 🧙🏼‍♂️
