passport (English)
Where does "passport" come from?
The English noun 'passport' entered the language from the French compound 'passeport'[1], which was formed by combining the verb 'passer', meaning 'to pass', with the noun 'port', meaning 'port'[1][3]. The first element descends through Middle French and Old French from Vulgar Latin '*passāre'[2][6], a verb formed from the Latin noun 'passus', meaning 'step'[6][13], which traces back to the Proto-Indo-European root '*peth₂-', meaning 'to spread'[7]. The second element comes via Old French from Latin 'portus'[4][8], which developed from Proto-Italic '*portus' and the Proto-Indo-European noun '*pértus', meaning 'crossing'[4][9]. Together, the elements originally conveyed the idea of authorization to pass through a port or gate before acquiring its modern sense as an official travel and identification document.
