From Middle English namely, nameliche, namelike, equivalent to name + -ly. Cognate with Saterland Frisian nämmelk, West Frisian nammentlik, Dutch namelijk, German Low German nämlich, German nämlich, Danish nemlig, Swedish nämligen, Icelandic nefnilega.
namely (not comparable)
A synonymous expression is the use of colon—":", as in "There are three ways to do it: the right way, the wrong way […]."
Since this is considered a dependent clause, a comma should follow the expression and either a semicolon or a comma should precede it, depending on the strength of the break in continuity. "Namely" can thus almost be considered a conjunction.
