Etymology
the word profligate originates from the latin verb 'profligare', meaning "to strike down, ruin". this verb is itself a compound of 'pro-' ("forward") and 'fligere' ("to strike"). the literal sense was to knock something down completely. in latin, the past participle 'profligatus' came to describe someone morally overthrown or ruined, hence "dissolute". this concrete image of being struck down evolved into the english abstract meanings of recklessly extravagant and morally degenerate, capturing the idea of a person who has "fallen" from virtue or financial prudence.
