Correct spelling for the English word "avari" is [avˈɑːɹi], [avˈɑːɹi], [a_v_ˈɑː_ɹ_i] (IPA phonetic alphabet).
Avari is a term originating from the Sindarin language, primarily used in the works of J.R.R. Tolkien in his fictional legendarium. In Middle-earth, Avari refers to the group of Elves who refused the summons of the Valar and did not complete the Great Journey to Valinor. The word itself can be translated to mean "the Unwilling" or "the Refusers."
The Avari Elves are portrayed as those who decided to stay in the Great Lands, embarking on their separate paths and lifestyles. They chose not to pursue the bliss and enlightenment promised by the Valar in Valinor, but instead maintained a connection to the mortal world and the chosen dwellings they established there. Tolkien described the Avari as more independent and less susceptible to the influence and guidance of the Valar.
Despite not having the direct guidance of the Valar, the Avari Elves did possess their own culture, languages, and societies. They were known for their love of nature and the untamed parts of Middle-earth. Throughout the history of Tolkien's world, the significance of the Avari Elves varied, but they played a minor role overall.
The concept of the Avari Elves is one of the many aspects of Tolkien's intricate mythology and adds depth to his imaginative realm. It showcases the diversity and complexity in the Elves' choices and association with different realms, providing a nuanced understanding of their place in the wider narrative.
