lieutenant (English)

Where does "lieutenant" come from?

The word lieutenant comes to us from Old French, combining 'lieu' meaning 'place' and 'tenant' meaning 'holder.' This literally translates to a 'place-holder,' tracing back to a deputy who stands in for another. Ultimately, the second half of the word stems from a Proto-Indo-European root meaning 'to stretch' or 'extend,' and it remains a linguistic sibling to the Latin phrase locum tenens.
