Gnomic poets are poets known for writing brief, pithy verses that express moral advice, practical wisdom, or general truths. Their work often reads like a chain of maxims or proverbs, meant to teach, warn, or sum up experience in a memorable way.
The word is usually used for early Greek poets such as Theognis or Hesiod when they write in this sententious, wisdom-centered style.
Example
Measure your anger before you measure your words;
A hasty tongue can split the quiet in two.
Trust the lamp that burns steadily, not the flare
that dazzles once and leaves the room in dark.
