So I've posted this same question in the Quenya forum, but I'd like to get something in Sindarin if I can.
Basically, given how much attention Tolkien pays towards celebrating and merry-making, I'm assuming that when he designed his languages he designed a way to express 'cheers' as well.
Does anybody know how to say this in Sindarin, or whether there's any reference in all the Tolkien lore as to any particular ritual associated with it (i.e. looking eye to eye, smashing beakers together, pouring some on the ground, etc.)?
