teniente
/teˈnjente/ · A2 · noun · m
lieutenant
🎖️ tener (to hold) + -iente = the one holding the post, like lieu-tenant
From tener, to hold, plus -iente, the Spanish -ing ending: literally holding. English lieutenant is the same idea from French: lieu (place) + tenant (holding), someone who holds the place of a superior. Hence also deputy.
