The story of the word
Coined as the counterpart to autotroph in turn-of-the-century plant physiology, it quietly defines every animal, including us, as something that cannot feed itself from raw materials. ἕτερος carries a distinction English lost: it means the other of exactly two, where ἄλλος means another out of many. That precision survives in heterosexual and in the chemist's heterogeneous, a mixture of two unlike things.
