A suffix of nouns, often corresponding to verbs ending in -ize or nouns ending in → -ism, that is used to form an agent noun indicating adherence to a certain doctrine or custom, practicing a particular skill or profession, and so on.

From Fr. -iste, from L. -ista, from Gk. -istes.

-bâvar, from bâvar "belief;" Mid.Pers. wâbar "belief;" Proto-Iranian *uar- "to choose; to convince; to believe;" cf. Av. var- "to choose; to convince" varəna-, varana- "conviction, faith;" O.Pers. v(a)r- "to choose; to convince;" Skt. vr- "to choose," vara- "choosing."
-gerâ, from gerâyidan "to incline toward; to intend; to make for," infinitive of gerâ, the etymology of which is not clear. Gerâ may be a variant of Mod.Pers. kil "bent, inclined" (k/g and l/r interchanges), from PIE base *klei- "to lean, incline," cognate with L. clinare "to bend" (E. declination, inclination, etc.), Gk. klinein "to cause to slope, slant, incline," Skt. sri- "to lean," O.Pers. θray-, Av. sray- "to lean," (cf. Ger. lehnen, E. lean).
