Why was "tantrum" trending last week?
formed in English c.1600, from pedant + -ic. The French equivalent is pédantesque. Perhaps first attested in John Donne's "Sunne Rising," where he bids the morning sun let his love and him linger in bed, telling it, "Sawcy pedantique wretch, goe chide Late schooleboyes." Related: Pedantical (1580s); pedantically.
