The state of being in agreement with facts or reality; something that is real and not false.
From Old English *trēowth* “faith, loyalty, veracity,” from *trēowe* “faithful, true.” It originally mixed the ideas of factual accuracy and personal faithfulness.
In older English, being “true” was as much about keeping promises as getting facts right. Modern debates about truth on the internet show we still struggle with both: what actually happened, and who we can trust to tell us.
