x1=t1=p2=p3=l2=v2 is a big-endian / most-significant-first tanru formed with x3=t2 modifying x2=t3=l1=v1, giving meaning x4=t4 in usage/instance x5=t5=v3.
When used as a language feature (with baunpli, e.g. «.i mi baunpli la vajli'epoitau le vi selsku»), according to this definition, reverse tanru order, so that without co the first (left) side becomes the tertau and the second (right) side becomes the seltau, and with co the second (right) side becomes the tertau and the first (left) side becomes the tertau; only tanru ordering is reversed, and not grammar (in particular tanru grouping and associativity, e.g. with bo and co, which retain their right-associativity) or lujvo. Note that since tanru order is reversed relative to CLL Lojban, meaning might be more easily confused unless this feature's usage is explicit. ni'o See also: vajyje'ipoitau (little-endian tanru), co'i'e'au'i («sei baunpli be la vajli'epoitau»), vajli'epoi (big-endian).
