Origin:
early 19th century: probably from the name of Jeremy Diddler, a character in the farce Raising the Wind (1803) by the Irish dramatist James Kenney (1780–1849). Diddler constantly borrowed and failed to repay small sums of money: the name may be based on an earlier verb diddle ‘walk unsteadily’.
