Fake Etymologies

Interesting is better than true.

ton‧ic, n. /ˈtɒnɪk/

From English “tone,” in the sense of a musical note. Opera singers would drink a special variety of sparkling mineral water before performaces, with the belief that it would help them hit notes more easily. This belief was demonstrated to be untrue, so the manufacturers pivoted by adding sugar and marketing to the general public. (See “soda,” “pop,” “soda pop.”)
