Origin Story

Era
From an everyday idiom

Muteokdaego breaks into three parts. Mu (無) means "without," teok means a standard or yardstick, and daego means "to press up against" or "to lunge at." The interesting piece is teok. Originally a native Korean word, teok pointed to the standard, the reason, or the proper measure of a thing — a sense that still survives in teok-eopda ("to make no sense, to be unreasonable"). So muteokdaego means "to press ahead with no standard or reason at all." It is hard to find a more precise way to describe someone who throws themselves into a task or charges in with no plan and no measure to guide them.

Another place teok carries the sense of "standard" is teokdo eopda ("not even close"), an older relative of eorim-eopda. It means falling far short of the mark — and here too, teok stands for the measure one fails to reach.
