commodore

The word 'commodore' has a fascinating journey from a title of courtesy to an official naval rank. It originates from the French 'commandeur', meaning 'commander', which itself evolved from the Medieval Latin 'commendator', meaning 'one who is entrusted' or 'a patron'. The Latin root is 'commendare', a compound of 'com-' (intensive) and 'mandare' (to entrust, order). The spelling was later influenced by folk etymology, associating it with the Latin 'modus' (measure), suggesting the 'one who sets the measure' or leads with others. This blend of ideas—entrusted authority and measured leadership—solidified in 17th-century English to denote the commander of a squadron or a senior naval captain, a rank between captain and rear admiral.
