anglo
x1 reflects proto-English/Jute-Anglo-Saxon culture (non-Celtic peoples of Great Britain arriving and settling from near Germany approximately between A.D. 500 and A.D. 800, or cultural descendants/relatives thereof) in aspect x2
anseingu
x1 (node in a tree graph) and x2 (node in the same tree graph) have an essentially-unique most recent (graph-nearest) common ancestor node A such that x3 [nonnegative integer; li] is d(A, x1) and such that x4 [nonnegative integer; li] is d(A, x2), where d is the graph geodesic distance (defined to be infinite if nodes are not connected in the correct direction).

tseingu
x1 (node in a tree graph) and x2 (node in the same tree graph) have an essentially unique most recent (graph-nearest) common ancestor node A such that x3 [nonnegative integer; li] is the minimum element of the set consisting only of d(A, x1) and of d(A, x2), and such that x4 [integer; li] is d(A, x1) - d(A, x2), where d is the graph geodesic distance (defined to be infinite if nodes are not connected in the correct direction).
cia'o'e
mekso 4-nary operator: spherical harmonics on colatitudinal/polar angle a and azimuthal/longitudinal angle b of unassociated order c and associated order d.

x1 is any child of the first child of the first child of ... the first child of x2, where the graph geodesic through the ancestorship-directed family tree from x1 to x2 is of length (x3) + 1 (li; x3 must be a nonnegative integer or positive infinity), and where "first" is according to (partial) ordering rule x4 (default: chronological order of birth per successive generation within the given lineage; other restrictions on legitimacy etc. may be specified here as well).
pavmompazy'utka'ypanzi
x1 is any child of the first child of the first child of ... the first child of x2, with intermediate steps x3 (complete ordered list, "ce'o"; should include the relevant parent of x1), where "first" is according to (partial) ordering rule x4 (default: chronological order of birth per successive generation within the given lineage; other restrictions on legitimacy etc. may be specified here as well).

.utkakpu
x1 and x2 are path-connected by ordered binary relation/predicate x3 (ka), such that all paths which satisfy condition(s) x4 (ka; default: no additional conditions) in the relevant graph (x5) linking nodes by said relation x3 in a directed manner and which contain x1 must also (later in the path) contain x2.
