(electronic + Gr. onyma, name;
cf.
pseudonym, synonym) -- electronic name; the part of electronic
address that precedes the sign @.
In our university mail
system, all elonyms are made from the first name initial plus the surname minus last letter. My elonym is bjohnso (Bill
Johnson).
His elonym is as enigmatic as he is himself: aaa314. Clearly he claims to be
alpha, not omega.
