Etymology
The English language word pedant comes from the Frenchpédant or its older mid-15th century Italian source pedante, 'teacher, schoolmaster'. The origin of the Italian pedante is uncertain, but several dictionaries suggest that it was contracted from the medieval Latinpædagogans,present participle of pædagogare, 'to act as pedagogue, to teach' . The Latin word is derived from Greek παιδαγωγός, paidagōgós, παιδ- 'child' + ἀγειν 'to lead', which originally referred to a slave who escorted children to and from school but later meant "a source of instruction or guidance".
Connotation
The term in English is typically used with a negative connotation to refer to someone who is over-concerned with and whose tone is :wikt:condescension|condescending. Thomas Nashe wrote in Have with you to Saffron-walden, page 43: "O, tis a precious apothegmaticall Pedant, who will finde matter inough to dilate a whole daye of the first inuention of Fy, fa, fum". However, when the word was first used by Shakespeare in The Taming of the Shrew, it simply meant "teacher".
