e/By Jingo

Information
has gloss	eng: The expression "by Jingo" is apparently a minced oath that appeared rarely in print, but which may be traced as far back as to at least the 17th century in a transparent euphemism for "by Jesus". The OED attests the first appearance in 1794, in an English edition of the works of François Rabelais as a translation for the French par Dieu! ("by God!").
