However, there are some archaic or dialectal variations that you might encounter in old texts or regional speech:
* Luer: This was an older spelling of "lure" that is no longer commonly used.
* Lour: This word, while spelled similarly, has a different meaning, referring to a gloomy or frowning expression.
So, while "lure" is the only standard spelling, these variations exist. However, it's best to stick with "lure" in modern English.
