commander

The word 'commander' has a direct lineage from Latin, entering English via Old French. Its core is the Latin verb mandare, meaning "to order, entrust, commit", which itself is a compound of manus ("hand") and dare ("to give"), thus literally "to give into one's hand". The intensive prefix com- ("with, thoroughly") was added to form the Late Latin commandare, strengthening the sense to "to order authoritatively". The agent suffix -er was then appended in Old French (comandeor) and Middle English to denote the person who issues such orders. The term's evolution from a literal act of handing over a duty to the modern abstract concept of holding supreme authority reflects the consolidation of power and responsibility in a single figure.
