x1 is a sibling of a direct ancestor/elder of x2 by bond/tie/relation/standard x3 (not necessarily genetic/biological nor necessarily directly ancestral); x1 is an associated member of one of x2's ancestor's generation; x1 is an (great-(great-(...)))uncle/aunt of x2.
Works for any nonnegative integer (including 0) number of "great-"s concatenated with any of the following: "uncle", "aunt", "nephew", "niece". Ancestor relationship may not be biological (it could be a string of adoptions, cultural/tribal leadership roles, biological parenthood, or any combination thereof); siblinghood may not be biological either. This word unifies the peripheral generalization/metaphoric sense of ".abvele" (understood to refer to a great-uncle or great-aunt, or the reciprocal relationship) with the meaning of "famti". It cannot refer to a sibling or a cousin (strict sense) of x2 in a simple family tree. See: .abvele, famti, tunba, tamne.
