altruism
UK: ˈæltruɪzəm | US: ˈæltruɪzəm
n. the principle or practice of selfless concern for the well-being of others
n. (in biology) behavior by an animal that benefits others at its own expense
The word altruism was coined in the 19th century by French philosopher Auguste Comte, derived from the Italian altrui (meaning "of others"), which itself traces back to Latin alter ("other"). Comte contrasted altruism with egoism to describe selfless behavior. The suffix -ism frames it as a philosophical or ethical principle. The term later entered biology to describe behaviors that benefit others at the organism’s own cost.
