illusion
  سفمان   
safmân (#)

Fr.: illusion   

1) A false sense impression of something actually present.
2) Something that produces a false or misleading impression of reality. → optical illusion.
3) An instance of being deceived.

From O.Fr. illusion "a mocking," from L. illusionem (nom. illusio) "a mocking, irony," from illudere "to mock at," literally "to play with," from in- "at" + ludere "to play," from ludus "a game, play;" PIE base *leid- "to play, jest."

Safmân, literally "wrong thought, ~ idea," from saf "wrong" (Tâleši), → false, + mân "thought," → idea.

image
  ۱) وینه، تصویر؛ ۲) وینه گرفتن، ~ برداشتن   
1) vine, tasvir (#); 2) vine gereftan, ~ bardâštan

Fr.: image   

1) In an optical system, the point to which light rays are converged (real image) or from which they appear to diverge (virtual image) after reflection or refraction.
Math.: A number, point, or unique element of a space that corresponds to some other number, point, or unit element.
2) To make an image of; to picture or represent in the mind.

From O.Fr. image, from L. imaginem (nom. imago) "copy, picture, likeness " from stem of imitari "to copy, imitate," from im-, stem of imitare "to copy, imitate" + -ago noun suffix.

1) Vine, from (Sorani) Kurd. vina or vena "image, picture; similar," from vin/ven, variant of bin, present stem of dîtin, Pers. didan "to see, to look;" cf. Taleshi vinde "to see," Tati vindiyan "to see," Persian bin-, didan "→ see." The relation between "image" and "see" is probably from the fact that the image of a subject can be seen without its presence.
