Note: Though the above is the only likely etymology, the formation is peculiar, as the suffix -ant is normally associated with verbs of French and/or Latin origin. This peculiarity suggests a deliberate coinage, but its source is apparently unknown. The word is attested earliest in Philadelphia city ordinances from the first decade of the nineteenth century.
