influence
  ۱) هنایش؛ ۲) هناییدن   
1) hanâyeš (#) ; 2) hanâyidan (#)

Fr.: 1) influence; 2) influencer, influer   

1) The act or power of producing an → effect, especially inconspicuously; the effect of power exerted.
2) To have or exert influence on; affect.

M.E., from O.Fr. influence, from L. influentia "stellar emanation" (it was thought an ethereal liquid flowed from the stars and affected the destiny of humans), also "a flow of water, a flowing in," from L. influentem (nominative influens), pr.p. of influere "to flow into," from → in- "into, in, on, upon" + fluere "to flow;" PIE base *bhleu- "to swell, overflow;" cf. Gk. phluein "to boil over, bubble up," phlein "to abound."

Hanâyeš "influence" (Borhân-e Qâte'; Kasravi). We suggest the following origin for this word: ultimately from Proto-Ir. *ha-nai "to conduct, direct, guide, lead," from *ham-naiH-, from prefix *ham- "together," also an intensive prefix, → com-, + *naiH- "to lead, conduct, guide;" cf. Av. naii- (naŷ-) "to lead, guide," naiieiti "leads;" O.Pers. nay- "to lead, bring" anaya "leads;" Mid.Pers. nidan, ônidan, nay- "to lead, bring;" Sogd. n'y- "to lead;" Choresmian (prefixed, + *apa-) bny- "to remove;" Skt. nī- "to lead," náyati "leads." In dialects: Anâraki niye "to bring, lead;" Kurd. (prefixed) ânin, inân, (with prefix ham-) hânin, hênân "to bring, lead to," Tâleši ânân, ânoe "to bring together two edges;" Zazaki ân- "to bring;" Qohrudi hunda, hun- "to bring, lead;" Târi niya-, neg- "to lead;" Lasgardi (prefixed) bin- "to bring, carry;" Qomi niyé, Tafreši neyé "a jab or poke used for leading the cattle;" see also → relate.

sphere of influence
  سپهر ِ هنایش   
sepehr-e hanâyeš

Fr.: sphère d'influence   

The region of space around one of the bodies in a system of two celestial bodies where a third body of much smaller mass is influenced by the gravitational field of that body. The sphere of influence of a planet with respect to the Sun has a radius given by: R = RP(MP/MS)2/3, where RP is the radius of the planet's orbit around the Sun, MP is the mass of the planet, and MS is the solar mass. The sphere of influence of the Earth has a radius of about 927,000 km or slightly under 150 Earth radii. Beyond this limit, a space probe will come under the influence of the Sun.

→ sphere; → influence.
