nym definition
A nym (pronounced NIHM and a shortened form of pseudonym,) is a name invented by or provided for an Internet user in order to conceal the user's real identity and, in some cases, to expressly create a new and separate Internet identity. Among reasons to have and use a nym are these: 1  You want to comment or take part in controversial political or other discussions on the Internet without revealing your opinions to colleagues, friends, or employers. 2  You want to send spam (unrequested bulk e-mail) without anyone being able to trace it to you.
