The next sentence in the 15th Conlang Relay Text:
ewaþ ñaxxa jajāra jaxālāe jatēnnen nā ñe janaren;
anxālāe appears here in the inanimate singular, modifying the word jajāra “dance”. anxālāe as an attribute refers to something as it should be, which would be “orderly, in harmony, balanced, fair”. As a modifier for “dance”, “in harmony” is probably the best pick.
