1588, "schoolmaster," from M.Fr.
pédant (1566), from It.
pedante "teacher, schoolmaster," apparently an alteration of L.L.
paedagogantem (nom.
paedagogans), prp. of
paedagogare (see
pedagogue). Meaning "person who trumpets minor points of learning" first recorded 1596.
Pedantic formed in Eng. c.1600, in 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."
