From Gk. mnemonikos "of or pertaining to memory," from mnemon "remembering, mindful," from mnasthai "remember," from PIE base *men- "to think;" cf. Pers. man-, -mân, minu, → idea.

Yâdsepâr, stem of Yâdsepârdan "memorize," from yâd "remembrance, recollection, memory" (Mid.Pers. ayâd) + sepârdan, sepor- "to yield, give, hand over" (Mid.Pers. abespâr- "to hand over, entrust;" cf. O.N. spara, O.H.G. sparon, O.E. sparian, E. spare); yâdsepârik, → mnemonics.

mode
  ترز، طرز، مُد   
tarz, mod

Fr.: mode   

1) Physics: Any of the distinct patterns of oscillation that a given periodically varying system can have.
2) Math.: In a series of statistical data, the item or value which occurs most frequently. It is a measure of central tendency.

Mode, from Fr. mode, from L. modus "measure, rhythm, song, manner," from PIE base *med- "to measure, limit, judge, advise;" cf. L. meditari "to think or reflect upon, consider;" Av. mad- "to measure out, apportion, allot;" Gk. medein "to rule;" O.E. metan "to measure out."

Tarz "manner, mode," Arabicized as طرز. Tarz may be related to Av. darəsa- "appearance, looking" (huuarə.darəsa- "having the appearance of the sun"), from Av. darəs- "to look;" cf. Skt. darś-, drś- "to see, appear, look, show" darśa- "apperance, look," drśta- "apparent, visible."
Mod, loan from Fr., cognate with Av. mad- "to measure out, apportion, allot," as above.

model
  ۱) مدل، ترزال؛ ۲) مدل‌ساختن، ترزالیدن   
1) (n.) model, tarzâl; 2) (v.) model sâxtan, tarzâlidan

Fr.: 1) modèle; 2) modéliser   

1a) A mathematical representation of a process, system, or object developed to understand its behavior or to make predictions. The representation always involves certain simplifications and assumptions. See also → theory, → hypothesis.
1b) A mental image of a phenomenon using familiar terms (or images). For example, in the Bohr model the atom is visualized as a nucleus with electrons orbiting around it in a manner similar to the way that planets revolve around the Sun. While this model is use ul in understanding the atom, it is an over-simplified description of a real atom and does not describe/predict all of its attributes (G. Smooth, Lawrence Berkeley Lab website).
2) To make or construct a model of.

M.Fr. modelle (Fr. modèle), from It. modello "a model, mold," from V.L. *modellus, from L. modulus "measure, standard," from modus "manner, measure" (cf. Av. mad-, → mode), PIE *med- + -ulus, → -ula.

1) Model, from Fr. modèle. Tarzâl, from tarz, → mode + -âl, → -al.
2) Model sâxtan, from model + sâxtan, sâzidan "to build, make, fashion; to adapt, adjust, be fit" (from Mid.Pers. sâxtan, sâz-, Manichean Parthian s'c'dn "to prepare, to form;" Av. sak- "to understand, to mark," sâcaya- (causative) "to teach").
Tarzâlidan, from tarzâl + -idan infinitive suffix.
