"If a legal party ... doesn't like a district court ruling, it is free to challenge the decision to a federal appellate court and then the Supreme Court. But while the appeal plays out, the legal party must abide by the ruling." — Will Rogers, The Baltimore Sun, 22 July 2025

Abide has abided in the English language since before the 12th century, picking up along the way several meanings and inflections that are now rare or no longer in use. For instance, one of abide's former meanings was "to stop" and its former past participle was abidden (whereas we now use abided or abode). Today, abide often turns up in the phrase "can't abide" to say that someone cannot tolerate or accept something. The expression abide by, which means "to accept and be guided by (something)," is also common. Related terms include abiding, meaning "continuing for a long time" or "not changing" (as in "an abiding friendship"), abidance ("continuance" or "the act or process of doing what you have been asked or ordered to do"), and abode ("the place where someone lives").
