μέν,

conjunctive particle (originally a form of μήν), usually related to a following δέ or other adversative conjunction, and distinguishing the word or clause with which it stands from that which follows.

It is generally untranslatable and is not nearly so frequent in NT as in cl. Like δέ, it never stands first in a clause.
