What do we call a concise statement that often offers advice or expresses a general truth?

The term that best describes a concise statement that often offers advice or expresses a general truth is maxim. A maxim is typically a short, pithy saying that conveys a practical principle or moral lesson, making it both memorable and applicable. The nature of a maxim allows it to serve as guidance in various situations, which is why it is recognized for its advisory character.

While a proverb, adage, and epigram share similarities with a maxim, they have distinct characteristics that set them apart. Proverbs often have cultural origins and are passed down through generations, emphasizing wisdom derived from collective experience. An adage is a type of proverb that typically conveys a traditional wisdom or truth, often implying a longstanding acceptance in a particular culture. An epigram, on the other hand, is usually more focused on wit or irony, often employing clever wordplay, making its primary purpose more about artistic expression than conveying a straightforward moral or piece of advice.

Thus, the definition aligns most closely with the concept of a maxim, highlighting its role in providing concise guidance or stating universal truths.
