USA, 1808—an irritation in the throat suggestive of an obstruction, producing a temporary croakiness or hoarseness—occasionally associated with the French, probably because ‘frog’ is derogatorily applied to them
UK, 1836—that’s a surprisingly unfair criticism, considering that the person who has just made it has the same fault—here, ‘rich’ means ‘preposterous’, ‘outrageous’
a movement, developed in the U.S.S.R. in 1935, aimed at encouraging hard work and maximum output, following the example of Alexei Stakhanov—by extension: exceptionally productive work, excessively intensive work
late 19th century—to disappear suddenly without leaving information about one’s whereabouts—from conjuring, in which ‘vanishing act’ designates an act of making a person or thing disappear as if by magic, and an act of disappearing in this manner

Australia, 1943—a foolish or silly person—from the synonymous noun ‘dill’ (1933), itself apparently a back-formation from the adjective ‘dilly’, meaning ‘foolish’, ‘silly’
