   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.

Etymology (EN): 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.

Etymology (PE): 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.
Tasvir, loan from Ar.

2. Infinitive with gereftan “take,” → take, and dâštan “to have, to hold,” → property.
