Forms
expedītus (feminine expedīta, neuter expedītum, comparative expedītior, superlative expedītissimus); first and second declension[2]
Etymology
It is the participle of expediō (“to free the feet, disentangle”), used as an adjective.[2][3][1] The verb is formed from ex- (“out of”) and pēs (“foot”); de Vaan explains its meaning from compedēs (“fetters”), so “to free from fetters”.[1][4] He traces the noun for foot to Proto-Indo-European *pōd-s, cognate with Ancient Greek πούς (poús) and Sanskrit पाद् (pā́t).[4]
Earliest recorded meaning
Cicero, writing from his province: expedītō exercitū ita noctū iter fēcī, “I marched by night with my army unencumbered”.[2][5]
Semantic evolution
The word is at home in the army: troops expedītī are free of baggage and ready for action, and used as a noun expedītus is a light-armed soldier.[2][1][6] Cicero also uses it of a traveller without luggage: Clodius met Milo expedītus, in equō, with no carriage and no wife.[2] From freedom of movement came agile (Varro), quick and ready in mind or speech (Cicero), free from difficulty and easy, of tasks and of roads (Caesar), and ready to hand, with in expedītō “in readiness”.[2]
Church Latin glosses it “well-appointed, light-armed”.[6]
