The story of the word

Greek kept two words apart that English collapses into 'other': ἄλλος is another out of many, ἕτερος is the other one of a pair. That precision is why heterosexual literally says 'of the other one of the two', and why a heteroclite noun bends one way and then the other. The word entered English in the 1620s alongside its twin homogeneous, and statisticians still use the pair daily.
