'true' originates from Old English, specifically the word 'trēow' (also spelled 'triewe'), where it meant 'faithful' or 'trustworthy', and ultimately from Proto-Germanic '*trewwiz'.

'true' changed from the Old English word 'trēow' to Middle English 'trewe', and eventually became the modern English word 'true'.

Initially, it meant 'faithful' or 'steadfast', but over time it broadened to include meanings related to accuracy and correspondence with fact: 'in accordance with reality'.
