Etymology
the word 'moxie' originated as a trademark for a bitter, non-alcoholic beverage marketed as a tonic and nerve food in the late 19th century. the drink's advertising, which touted its invigorating and restorative properties, led to the name being associated with vigor, energy, and courage. by the 1930s, 'moxie' had fully entered the common lexicon, shedding its commercial origins to denote spirited determination and pep. its journey from a specific brand name to a general term for fortitude is a classic example of genericization.
