peace (English)

Where does "peace" come from?

The English word 'peace' traces its roots back to the Proto-Indo-European root *peh₂ḱ-, meaning 'to fasten' or 'to join,' which suggests that true peace is a state of coming together. It evolved through the Latin 'pāx' and Old French 'pais' before entering Middle English as 'pees.' Along its journey, 'peace' displaced native Old English terms like 'sibb' to become our modern standard for describing harmony and the absence of conflict.
