Did you know?

Steadfast has held its ground for many centuries. Its Old English predecessor, stedefæst, combines stede, meaning "place," and fæst, meaning "fixed." Steadfast was first used in battle contexts to describe warriors who literally stood their ground, which led to its "immovable" sense, as when Sinclair Lewis wrote of "a castle, steadfast among storms." (The word was also once used to describe steady hands, as well as substances that keep their solid, firm state.) These senses were soon joined by one applied to people's character, implying unswerving faith, loyalty, or devotion; arriving in the 12th century, this meaning has remained steady in the English language ever since.
