diplomacy (English)
Where does "diplomacy" come from?
The English noun diplomacy comes from French 'diplomatie'[1][3], which was formed as a back-formation from 'diplomatique'[1]. This French family traces back to New Latin 'diplomaticus'[8] and ultimately to Latin 'diploma', meaning 'letter of recommendation or authority'[1]. The Latin term itself was borrowed from Ancient Greek 'δίπλωμα', meaning 'folded paper, license'[2], which derives from the verb 'διπλόω' meaning 'I double'[4]. This Greek root goes back further through 'διπλόος' ('double')[5][6] and 'δίς' ('twice')[6], eventually descending from the Proto-Indo-European root '*dwís'[7], which originated from '*dwóh₁' meaning 'two'[9].
