dromedary

Origin

From Middle English dromedari, dromedarie (“dromedary; any camel”) [and other forms], from Old French dromedaire, from Late Latin dromedārius (“kind of camel”), from Latin *dromadārius, from dromas, dromadis (“dromedary”) + -ārius (suffix forming nouns denoting agents of use). Dromas and dromadis are derived from Ancient Greek δρομᾰ́ς (dromắs, “running; dromedary”), an ellipsis of δρομὰς κάμηλος (dromàs kámēlos, “running camel”), from δρόμος (drómos, “race, running; race course, track”), ultimately from Proto-Indo-European *drem- (“to run”).
