We’re on this sentence in the 15th Conlang Relay Text:
ewaþ ñaxxa jajāra jaxālāe jatēnnen nā ñe janaren;
janaren is an indefinite pronoun meaning “everything”. The full phrase nā ñe janaren is literally “more than everything” and means “most [of all]”. So jajāra jaxālāe jatēnnen nā ñe janaren is “the most graceful and harmonious dance of all”. And ewaþ ñaxxa is “Yet they make”.
“Yet they make the most graceful and harmonious dance of all.”
