Aberri Eguna
"Aberri" is a neologism coined by Sabino Arana based on the suffix "-ba" which occurs in numerous kinship terms (e.g. "osaba" "uncle", "izeba" "aunt", "arreba" "sister of a man" etc.) from which he fancifully deduced a putative root *aba "father". He formed numerous neologisms based on this putative word such as "aberri" (*aba + "herri" "land, people, country, settlement"), "abizen" "surname" (*aba + "izen" "name") or "abenda" "race" (*aba + "enda" "lineage"). From "aberri" he then went on the coin "abertzale" "patriot" ("aberri" "fatherland" + "-(t)zale", a suffix denoting someone keen on something). In spite of their fanciful derivation, "aberri" and "abertzale" have found their way into general usage.
