x1=sr1=m1=se2 errs in being identical to x2=m2 (object/person), an error under conditions x3=sr3 by standard x4=sr4=m3; x1 loses themselves in being x2; x1 errs in being a clone, caricature of x2; x1 has an identity crisis, typecasts themselves.
Copied from gleki's definition of mitsre and modified. Regarding which possible meaning is chosen for mitsre, it is proposed to be a shortening of sezmitsre (analogous, with kaisre, to dubybi'o vs kairbi'o) as opposed to mazdu'osre (analogous to dubyfa'i, being mazdubyfa'i rather than sezdubyfa'i). See also: mazdu'osre, mitsre, kaisre, sevzi.
