zunle -zul- gismu

x1 is to the left/left-hand side of x2 which faces/in-frame-of-reference x3.

Also x3 is the standard of orientation for x2. See also cmavo list zu'a, pritu, mlana, crane, trixe, farna.

In notes:

crane
x1 is anterior/ahead/forward/(in/on) the front of x2 which faces/in-frame-of-reference x3.
farna
x1 is the direction of x2 (object/event) from origin/in frame of reference x3.
mlana
x1 is to the side of/lateral to x2 and facing x3 from point of view/in-frame-of-reference x4.
pritu
x1 is to the right/right-hand side of x2 which faces/in-frame-of-reference x3.
trixe
x1 is posterior/behind/back/in the rear of x2 which faces/in-frame-of-reference x3.
bavyfa'a
x1 is futureward/to the futureward side/in the future of x2 in frame of reference/according to observer or vantage point x3.

x1 is so x2 (ka) that x3 (nu); x1=ckajiZ1=ckajiP1=raunzu1 satisfies property x2=ckajiZ2=fatci1=raunzu2=zmadu2 enough that x3=raunzu3, where ckajiP2=kanpe2=zmadu2.
selskusku
x1=skuP1 says x2=skuP2=skuZ2 to x3=skuP3 via medium x4=skuP4, quoting x5=skuZ1 saying that to x6=skuZ3 via medium x7=skuZ4.
zucna
x1 is counterclockwise/left-turn-direction of[/to] x2 along/following track x3 [path] in frame of reference x4 (where the axis is within the region defined by the track as the boundary, as viewed from and defined by view(er) x4; see notes); x1 is locally to the left of x2, according to x4, constrained along x3; x1 is along a left turn from x2 along path x3, as viewed in frame x4.
