Ermentrude [Ermentrude 词源字典]: fem. proper name, from Old High German Ermentrudis, from ermin "whole, universal" + trut "beloved, dear."[Ermentrude etymology, Ermentrude origin, 英语词源]
ermine (n.): late 12c., from Old French ermine (12c., Modern French hermine), used in reference to both the animal and the fur. Apparently the word is a convergence of Latin (mus) Armenius "Armenian (mouse)" -- ermines being abundant in Asia Minor -- and an unrelated Germanic word for "weasel" (represented by Old High German harmo "ermine, stoat, weasel," adj. harmin; Old Saxon harmo, Old English hearma "shrew," etc.) that happened to sound like it. OED splits the difference between competing theories. The fur, especially with the black of the tail inserted at regular intervals in the pure white of the winter coat, was used for the lining of official and ceremonial garments, in England especially judicial robes, hence figurative use from 18c. for "the judiciary." Related: Ermined.
erne (n.): "sea eagle," from Old English earn "eagle," from Proto-Germanic *aron-, *arnuz "eagle" (cognates: Old High German arn, German Aar, Middle Dutch arent, Old Norse örn, Gothic ara "eagle"), from PIE root *or- "great bird" (cognates: Greek ornis "bird," Old Church Slavonic orilu, Lithuanian erelis, Welsh eryr "eagle"). The Germanic word also survives in the first element of names such as Arnold and Arthur.

erode (v.): 1610s, "gnaw or eat away" (transitive), a back-formation from erosion, or else from French éroder, from Latin erodere "to gnaw away, consume," from assimilated form of ex- "away" (see ex-) + rodere "gnaw" (see rodent).

erogenous (adj.): "inducing erotic sensation or sexual desire," 1889, from Greek eros "sexual love" (see Eros) + -genous "producing." A slightly earlier variant was erogenic (1887), from French érogénique. Both, as OED laments, are improperly formed. Erogenous zone attested by 1905.
In this connection reference may be made to the well-known fact that in some hysterical subjects there are so-called "erogenous zones" simple pressure on which suffices to evoke the complete orgasm. There is, perhaps, some significance, from our present point of view, in the fact that, as emphasized by Savill ("Hysterical Skin Symptoms," Lancet, January 30 1904) the skin is one of the very best places to study hysteria.
