313 From a letter to Michael Tolkien 

25 November 1969

I wish I had time to produce an elementary (! both languages are, of course, extremely difficult) grammar and vocabulary of 'elven': sc. Quenya and Sindarin. I am having to do some work on them, in the process of adjusting 'the Silmarillion and all that' to The L.R. Which I am labouring at, under endless difficulties: not least the natural sloth of 77+.
