One of a number of things, or a part of something, taken to show the character of the whole.

From O.Fr. essample, from L. exemplum "a sample," literally "that which is taken out," from eximere "to take out, remove," from → ex- + emere "to obtain, buy," originally "to take," from PIE base *em- "to take" (cf. Av. yam-, yās- "to hold, take hold of," apayeiti (with apa) "taking away a thing from;" O.Pers. āyasa- "to take as one's own;" Skt. yam- "to hold, sustain," yamati "holds, subdues;" O.C.S. imo "to take;" Lith. imti, ima, émé "to take").

Nemuné, from nemun "index; guide," from nemudan "to show, display," from Mid.Pers. nimūdan, from ne- "down; into;" O.Pers./Av. ni- "down; below; into," → ni-, + mun, Av. māy- "to measure," → display.
