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

Also: x3 is the standard of orientation for x2. See also cmavo list ri'u, mlana, crane, trixe, farna, zunle.

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.
trixe

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.
zulna
x1 is to the left of x2 as seen by x3; x1 is to the left of x2 in frame of reference x3
