Etymology<\/h3>\n

The word unprincipled is formed from the prefix “un-”<\/span> (meaning “not”<\/span>) and the word “principled”<\/span>, which comes from the noun “principle”<\/span>. “Principle”<\/span> derives from the Latin “principium”<\/span>, meaning “beginning, foundation, or source.”<\/span> Over time, “principle”<\/span> came to represent foundational truths or rules of conduct. Therefore, someone “unprincipled”<\/span> is one who lacks these foundational moral rules.<\/p>\n

The term has been used in English since the early 17th century to describe people whose actions are guided by selfishness or dishonesty rather than ethics.<\/p>\n
