The etymology of the word "altruistic", can, of course, be found in Latin, as many words in the English language can. It originated from the Latin "alteri huic", which means "to this other". Then it traveled to Italian, became "altrui", meaning "somebody else", and then to French, became "altruisme", which then became the English "altruism", meaning "selflessness".
