Writers should have words handy

 

The word steadfast has and Old English predecessor, stedefæst, combines stede (meaning "place" or "stead") and fæst (meaning "firmly fixed"). The word was first used in battle contexts to describe warriors who stood their ground, which led to its "immovable" sense. That sense gave way to the word's use as an adjective implying unswerving faith, loyalty, or devotion.

When the ancient Greeks used dēmagōgos (from dēmos, meaning "people," and agein, "to lead") they meant someone good—a leader who used outstanding oratorical skills to further the interests of the common people. But the word, demagogue, took a negative turn, suggesting one who uses powers of persuasion to sway and mislead.
