ermine (n.) Look up ermine at Dictionary.com
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.

erode (v.) Look up erode at Dictionary.com
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). Intransitive sense "become worn away" is by 1905. Related: Eroded; eroding. Originally of acids, ulcers, etc.; geological sense is from 1830.
erogenous (adj.) Look up erogenous at Dictionary.com
"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.
